Formaldehyde and VOC Testing Based on the Building, Suspected Source and Project Objective
Angstrom Testing Services LLC provides independent formaldehyde air testing, broader VOC sampling, chemical-odor assessment, indoor air quality consulting and written reporting for homes, apartments, condominiums, co-ops, offices, schools, daycares, health care facilities, laboratories, commercial buildings, property managers, attorneys and building owners.
Formaldehyde testing may be useful after installation of new cabinets, built-ins, furniture, composite wood, flooring, insulation, coatings, adhesives or other renovation materials. For unknown or mixed chemical odors, Angstrom can also coordinate evacuated-canister VOC testing with laboratory analysis by gas chromatography/mass spectrometry using EPA TO-15 or TO-15A procedures as appropriate.
Standard TO-15 or TO-15A reporting is based on the laboratory's calibrated target-analyte list. When a project involves an unexplained odor or a suspected compound that is not on that list, an optional tentatively identified compound (TIC) review may extend the investigation by screening additional GC/MS peaks against a mass-spectral library. TIC identifications are tentative and concentrations are generally estimates rather than compound-specific calibrated measurements.
Formaldehyde remains a separate analytical question. When formaldehyde is the primary concern, a dedicated DNPH/HPLC method such as NIOSH Method 2016 is generally preferred unless the laboratory has demonstrated suitable canister-method performance for formaldehyde.
Angstrom provides inspection, sampling, laboratory coordination, consulting and reporting. We do not sell air purifiers, ozone generators, filtration systems, sealants, odor treatments, renovation services or remediation products.
Common reasons to request testing
When Formaldehyde or VOC Air Testing May Be Useful
New Furniture and Flooring
Desks, wardrobes, beds, upholstered furniture, laminate flooring, engineered wood, underlayment and related products may contribute formaldehyde or other VOCs.
Recent Renovation or Fit-Out
Paints, coatings, adhesives, sealants, flooring products, wall systems, furnishings and stored construction materials may affect indoor air.
Spray Foam or Insulation Odors
Insulation-related complaints may involve aldehydes, amines or other VOCs. The scope should not assume that formaldehyde is the only possible source.
Persistent Chemical Odors
Strong, sweet, pungent, solvent-like, resin-like or unexplained odors may require source review, ventilation assessment, formaldehyde-specific sampling, TO-15 / TO-15A VOC analysis or optional TIC screening depending on the suspected source.
Schools, Daycares and Offices
Testing may support complaints involving new furniture, flooring, classroom materials, office fit-outs, portable buildings or inadequate ventilation.
Workplace Formaldehyde Use
Laboratories, mortuaries, health care settings, manufacturing, salons and other workplaces may require representative full-shift or short-term exposure monitoring.
Pre-Occupancy or Legal Documentation
Owners, buyers, boards, attorneys, insurers and facility managers may request independent measurements after construction or before occupancy.
Targeted formaldehyde, canister VOCs and expanded screening
Types of Formaldehyde and VOC Testing We Perform
The appropriate scope depends on the suspected source, property type, occupant or worker concern, ventilation conditions, sample duration, target compounds, required sensitivity, laboratory capabilities and intended comparison criteria.
Formaldehyde Air Testing
Formaldehyde-specific air samples may be collected in selected rooms and submitted for laboratory analysis using a method appropriate to the project.
NIOSH Method 2016 Sampling
Active air sampling uses DNPH-treated silica-gel media with laboratory analysis by high-performance liquid chromatography with ultraviolet detection.
EPA TO-15 / TO-15A VOC Testing
Whole-air samples may be collected in laboratory-prepared evacuated stainless-steel canisters and analyzed by GC/MS for the laboratory's calibrated VOC target list.
Read about canister VOC testingTentatively Identified Compound Review
When offered by the laboratory, TIC review can screen non-target GC/MS peaks against a mass-spectral library to suggest possible additional compounds beyond the calibrated target list.
Read about TIC limitationsAldehyde and Carbonyl Testing
Selected projects may include formaldehyde together with acetaldehyde or other carbonyl compounds when the analytical method and source history support it.
Source-Focused Room Sampling
Samples may be collected in rooms with cabinets, built-ins, furniture, flooring, insulation or other suspected materials and compared with other locations.
Pre-Occupancy & Post-Renovation Testing
Testing may document selected indoor-air conditions after construction, renovation, furnishing or fit-out and before regular occupancy or after a complaint develops.
Workplace Exposure Monitoring
Personal breathing-zone or area samples may be designed for representative workers, tasks, full shifts, short-term exposures or specific formaldehyde-using processes.
Ventilation and Building Review
The assessment may document windows, HVAC operation, outdoor-air delivery, exhaust, temperature, humidity and air movement that can affect concentrations.
Direct-Reading Screening
Screening instruments may help identify patterns or possible source areas, but cross-sensitivity and instrument limitations require cautious interpretation.
Indoor / Outdoor Comparison
An outdoor or unaffected comparison sample may be useful when interpreting a broader VOC pattern, background sources or building-related concentration differences.
Written Reports and Consulting
Reports may include the building history, methods, sample locations, conditions, calibrated target results, TIC findings when requested, limitations and next steps.
A reactive indoor air contaminant
What Is Formaldehyde?
Formaldehyde is a colorless, strong-smelling gas and a specific volatile organic compound. It is used in resins, adhesives, composite wood products, coatings, textiles, disinfectants, preservatives and many industrial processes. It is also produced by combustion and occurs at low levels in indoor and outdoor air.
Indoors, formaldehyde can be emitted from particleboard, medium-density fiberboard, hardwood plywood, cabinetry, furniture, flooring, wall systems, adhesives, finishes, fabrics and other products. Tobacco smoke and unvented combustion appliances can also contribute.
Because formaldehyde is a gas, its concentration cannot be determined by visual inspection. Odor may suggest that a chemical source is present, but odor strength does not identify the compound or provide a reliable concentration.
Emissions and measured concentrations may vary with the product, manufacturing process, material age, exposed surface area, temperature, relative humidity, ventilation, air exchange, room volume and recent installation.
Common indoor source categories
Materials and Activities That May Contribute Formaldehyde
Composite Wood Products
Particleboard, MDF, hardwood plywood, shelving, drawer components, furniture panels and other resin-bonded wood products.
Cabinets and Millwork
Kitchen cabinets, bathroom vanities, closets, wall panels, built-ins, custom millwork and concealed composite components.
Flooring and Underlayment
Laminate and engineered flooring, underlayment, adhesives, coatings and related installation products.
Furniture and Furnishings
Desks, beds, wardrobes, shelving, upholstered furniture, mattresses, fabrics and permanent-press textile treatments.
Renovation Products
Adhesives, sealants, coatings, paints, wall systems, insulation-related materials and stored construction products.
Combustion and Smoke
Tobacco smoke, gas appliances, kerosene heaters, fireplaces, vehicle exhaust and other combustion sources.
Laboratory and Health Care Use
Formalin, tissue preservation, pathology, disinfection, specimen handling and related occupational processes.
Hair and Cosmetic Products
Certain hair-smoothing or straightening products and heated salon processes may release formaldehyde.
Selecting the correct laboratory method
Formaldehyde-Specific Testing Versus Broader VOC Testing
NIOSH 2016 Formaldehyde
Designed specifically to measure formaldehyde using DNPH-treated sample media and HPLC/UV analysis.
- Formaldehyde is explicitly targeted
- Method sensitivity can be planned in advance
- Useful for residential and occupational scopes
- Does not identify the broader VOC mixture
EPA TO-15 / TO-15A
Whole air is collected in a specially prepared canister and analyzed by GC/MS for compounds on the laboratory's validated and calibrated target list.
- Evaluates many VOCs in one air sample
- Useful for unknown or mixed chemical odors
- Can be collected as grab or time-integrated samples
- Target lists and reporting limits vary by laboratory
TO-15 / TO-15A With TIC Review
GC/MS scanning can provide additional information about non-target peaks. When the laboratory offers TIC review, library searching may suggest possible identities.
- Can extend the investigative reach beyond the target list
- Useful for unexplained odors and unusual source histories
- Identities are tentative rather than target-confirmed
- Estimated concentrations are not equivalent to calibrated target results
Whole-air canister sampling and GC/MS analysis
EPA TO-15 / TO-15A VOC Air Testing
EPA TO-15 and the updated TO-15A describe collection of whole-air samples in specially prepared canisters followed by preconcentration and gas chromatography/mass spectrometry. Although developed for ambient-air applications, EPA TO-15A also recognizes applications such as indoor-air investigations when method performance requirements are met.
Evacuated Canister Sampling
Air is collected into a laboratory-prepared, specially cleaned stainless-steel canister. Depending on the project and flow controller, the sample may represent a short grab period or a longer time-integrated interval.
Target-Compound Analysis
The laboratory preconcentrates an aliquot of the air sample and uses GC/MS to separate, identify and quantify VOCs included on its calibrated target-analyte list.
Target Lists Vary
TO-15 / TO-15A is not one fixed commercial panel. Laboratories may calibrate different compound lists and reporting limits. The requested list should be reviewed before sampling.
Indoor-Air Applications
Canister VOC testing can support investigations involving solvents, fuels, coatings, adhesives, cleaners, furnishings, construction products and unexplained chemical odors.
TO-15 / TO-15A does not mean that every VOC in the room is quantitatively measured.
The laboratory's calibrated target list determines which compounds receive compound-specific quantitative results. TIC review can broaden the screening value of the GC/MS data, but it does not convert every chromatographic peak into a confirmed identity or fully calibrated concentration.

Formaldehyde-specific sampling and laboratory analysis
How NIOSH Method 2016 Formaldehyde Sampling Is Performed
Review the Complaint and Building History
We review the property, affected rooms, odors, installation dates, recent renovation, product information, ventilation, occupancy and testing objective.
Select the Method and Reporting Limit
Formaldehyde-specific DNPH sampling, broader TO-15 / TO-15A canister VOC testing, aldehyde analysis or a combined scope is selected before samples are collected.
Choose Representative Locations
Samples may be placed in bedrooms, kitchens, offices, classrooms, nurseries, source rooms, comparison areas or worker breathing zones.
Document Indoor Conditions
Temperature, relative humidity, windows, HVAC operation, outdoor-air conditions, recent cleaning, product use and occupancy may be recorded.
Collect the Air Samples
Calibrated pumps, validated passive samplers or laboratory-prepared canister systems are used according to the selected method. Field blanks and chain-of-custody documentation may be included.
Analyze and Interpret the Results
Laboratory results are reviewed with sample duration, reporting limits, target list, TIC findings when requested, building conditions, suspected sources and comparison data.
Source review, sampling and building conditions
Formaldehyde Results Must Be Connected to the Actual Indoor Environment
Variables that can change indoor concentrations
Temperature, Humidity, Ventilation and Product Age Matter
Temperature and Relative Humidity
Emissions from some materials can increase as temperature or humidity rises. Conditions during sampling should be documented and considered when comparing results collected on different days or seasons.
Ventilation and Outdoor Air
Open windows, exhaust fans, HVAC outdoor-air delivery, air exchange and room pressurization can dilute, redistribute or remove indoor formaldehyde.
Read about ventilation and carbon dioxideProduct Age and Installation
Emissions may be greatest after manufacture or installation and may decline over time, but the pattern depends on the product, coatings, exposed edges, room conditions and continued introduction of new materials.
Room Volume and Source Loading
A small room with extensive new cabinetry may differ from a larger room with fewer emitting surfaces. Sample location relative to the source can also affect results.
HVAC Operation and Air Mixing
Fan operation, recirculation, filtration, closed doors and supply or return placement may affect distribution among rooms and floors.
View indoor air quality testingRecent Activities and Products
Cleaning agents, fragrances, smoking, cooking, painting, stored chemicals and recent deliveries can affect odor and broader VOC results during the sampling period.
Workplace exposure criteria
OSHA Formaldehyde Exposure Requirements
0.5 ppm as an 8-Hour TWA
OSHA defines the formaldehyde action level as 0.5 part per million, calculated as an eight-hour time-weighted-average concentration.
0.75 ppm as an 8-Hour TWA
OSHA requires employers to prevent employee exposure above 0.75 ppm as an eight-hour time-weighted average.
2 ppm Over 15 Minutes
OSHA’s short-term exposure limit is 2 ppm measured over a 15-minute period.
Worker, Task and Shift Matter
Occupational samples should represent the employee’s full-shift or short-term exposure and the relevant job classification, work area and shift.
Open OSHA 29 CFR 1910.1048Occupational limits are not residential indoor-air standards.
OSHA criteria are workplace exposure limits designed for representative employee monitoring. They should not be presented as universal residential, school, daycare, pre-occupancy or medical pass/fail values. Non-occupational interpretation requires separate public-health, building and project context.
Indoor result interpretation
There Is No Single Universal Residential “Safe” Formaldehyde Level
Formaldehyde results may be compared with selected occupational limits, public-health guidelines, green-building criteria, agency reference values or project-specific goals. Those values were developed for different populations, durations and purposes and are not automatically interchangeable.
EPA’s TSCA Title VI standards regulate formaldehyde emissions from specified composite wood products and finished goods. Product-emission compliance is not the same as a direct measurement of indoor air in a particular apartment, school or office.
A measured concentration should be evaluated with the sampling method, reporting limit, duration, temperature, humidity, ventilation status, product history, source loading, occupant use and comparison locations.
When an odor or complaint involves several possible chemicals, a formaldehyde result alone may not resolve the source. Additional VOC, aldehyde, combustion, ventilation, moisture or building-system evaluation may be needed.

Important limitations
What Formaldehyde and VOC Testing Can and Cannot Establish
Air samples represent selected locations, durations and conditions at the time of collection. Results can change with temperature, humidity, ventilation, occupancy, material age, source activity, cleaning, product use and building operation.
A low or non-detect result for one sample does not prove that formaldehyde or VOCs are absent from every room, cabinet, wall cavity, furnishing, HVAC zone, work task, product or future operating condition.
A formaldehyde-specific result does not identify every chemical that may contribute to an odor or complaint. Conversely, a broad VOC result should not be assumed to provide valid formaldehyde data unless the laboratory method supports that analyte.
TIC review can extend screening beyond a calibrated VOC target list, but TIC identities are tentative and estimated concentrations are not equivalent to compound-specific calibration. A significant TIC may require follow-up with a targeted analytical method or authentic reference standard.
Direct-reading sensors may respond to other gases or environmental conditions. Screening readings should not replace laboratory confirmation when compound-specific data are needed.
Product compliance with TSCA Title VI or another emission standard does not guarantee a particular indoor-air concentration after the product is installed in a specific room.
Environmental testing does not diagnose illness, establish individual dose, prove that formaldehyde caused a symptom or calculate an individual cancer risk. Medical concerns should be addressed by an appropriate health care professional.

Frequently Asked Questions
What is formaldehyde air testing?
Formaldehyde air testing measures formaldehyde in a selected air sample. It may be used for concerns involving cabinets, furniture, flooring, renovation materials, workplaces, chemical odors or pre-occupancy conditions.
What is NIOSH Method 2016?
NIOSH Method 2016 collects formaldehyde on DNPH-treated silica gel. The formaldehyde derivative is analyzed by high-performance liquid chromatography with ultraviolet detection.
What is EPA TO-15 or TO-15A VOC testing?
TO-15 and TO-15A are EPA whole-air methods that use specially prepared canisters followed by preconcentration and GC/MS analysis. The laboratory quantitatively reports compounds included on its calibrated target list.
What are tentatively identified compounds, or TICs?
TICs are additional non-target GC/MS peaks that a laboratory may evaluate by comparing mass spectra with a reference library. The resulting identification is tentative and the concentration is generally an estimate rather than a compound-specific calibrated result.
Can TIC review find compounds that are not on the normal TO-15 target list?
It can broaden the screening value of the GC/MS data by flagging some compounds outside the calibrated target list when they produce suitable chromatographic and mass-spectral information. It does not identify every VOC, and important findings may require targeted confirmation.
Is formaldehyde testing the same as VOC testing?
No. Formaldehyde is one specific compound that commonly benefits from a formaldehyde-specific DNPH method. TO-15 / TO-15A testing evaluates a broader group of VOCs using canister sampling and GC/MS.
Can a TO-15 or TO-15A canister test measure formaldehyde?
Canister methods can present additional analytical challenges for formaldehyde, and laboratory target lists and method performance vary. When formaldehyde is the primary concern, a dedicated DNPH/HPLC method such as NIOSH 2016 is generally preferred unless the laboratory has demonstrated suitable canister performance.
Can an electronic formaldehyde or VOC meter replace laboratory testing?
Not necessarily. Direct-reading sensors may be useful for screening or source patterns, but cross-sensitivity and environmental effects can limit specificity. Laboratory sampling is preferred when defensible compound-specific data are needed.
Is there a universal safe residential formaldehyde level?
There is no single universally accepted residential pass/fail level. Results may be compared with selected public-health or building guidelines, but the duration, population, method and purpose of each value must be considered.
Can OSHA limits be used for an apartment or school?
OSHA’s formaldehyde criteria are occupational exposure limits based on representative employee monitoring. They should not be presented as universal residential, school, daycare or medical clearance values.
Can testing identify the exact source of a chemical odor?
Testing can narrow possible sources, but odor investigations often require building-history review, source inspection, ventilation observations, formaldehyde-specific sampling and broader VOC analysis. TIC review can add screening information when the routine target list does not explain the odor.
Will I receive a written report?
Yes, when included in the agreed scope. Documentation may include the project history, sample methods and locations, indoor conditions, formaldehyde results, calibrated VOC targets, TIC findings when requested, comparison context, limitations, photographs and recommendations.
What areas do you serve?
