Chemical Manufacturing Industrial Hygiene Testing
Worker exposure monitoring for formulators, specialty and batch chemical manufacturers, and coatings/resin producers — VOCs, isocyanates, formaldehyde and process acids/alkali analyzed in-house at our Houston lab, with 1-day rush and kits shipped anywhere in the U.S.
Why Chemical Manufacturers Run Their Monitoring With Us
Accredited & Defensible
AIHA-LAP analysis that holds up with OSHA, legal counsel and insurers.
Reactive-Chemistry Ready
Isocyanates, formaldehyde, acids/alkali and VOCs — the exposures specific to batch and specialty processes.
In-House, One Lab
Every analyte under one roof, one chain of custody, consistent methods across every plant.
1-Day Rush
Same-day log-in before 2 PM CST and rush to 1 business day when a result is time-sensitive.
Exposure Monitoring for Formulators & Specialty Chemical Producers
Chemical manufacturing covers a wide range of operations — coatings, adhesives and resin production, plastics and polymer compounding, agricultural and industrial formulation, and batch or continuous specialty chemical processes. Each carries its own exposure profile, but VOCs and solvent vapors, isocyanates, formaldehyde, and acid/alkali mist are the recurring analytes across the sector. AGT Labs is the accredited industrial hygiene lab behind that monitoring, analyzing every sample in-house in Houston.
Chemical manufacturing happens in every state, and the standards don't change with the zip code. We serve plants anywhere in the United States — kits ship out, samples come back by prepaid return label, and analysis is identical wherever it was collected.
Running a refinery or large petrochemical plant?
This page is built for chemical manufacturers, formulators and specialty/batch producers. For refineries and large-scale petrochemical operations, see our dedicated Turnaround & Shutdown and Routine Refinery & Plant Compliance programs, built around benzene, H₂S and refinery-specific logistics.
- VOCs and solvent vapors by sorbent tube / GC
- Isocyanates (MDI, TDI, HDI) by OSHA 42 / 47
- Formaldehyde by NIOSH 2016 / 3500
- Acids and alkali mist by ion chromatography
- Airborne metals by ICP-AES; respirable and total dust
- Asbestos (NVLAP bulk PLM; PJLA PLM/PCM) for legacy facilities
What We Analyze for Chemical Manufacturing Sites
Every analyte below is run in-house under accreditation. Tap any card for the full method detail on our service pages.
VOCs & Solvents
Sorbent tube / GC analysis for solvent and volatile organic compound exposure.
View Service →Formaldehyde
NIOSH 2016 (impinger) or 3500 (badge) for resin and preservative processes.
View Service →Acids & Alkali Mist
Ion chromatography for scrubber, neutralization and cleaning operations.
View Service →Total & Respirable Dust
Gravimetric particulate for powder handling and bagging operations.
View Service →Asbestos (PLM/PCM)
NVLAP (bulk PLM) & PJLA (PLM/PCM) for legacy plant renovation/demolition.
View Service →Chemical Manufacturing Analytes — OSHA vs ACGIH Limits
For several process analytes the OSHA limit and the health-based guideline are far apart. Both are shown, since most plants now set internal triggers against the lower number. These are federal limits and apply in every state.
