Our lab provides comprehensive Industrial Hygiene and Gas Testing services, backed by our ISO 17025 accreditation for the determination of metals and metalloids in airborne particulate matter using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), following Modified NIOSH 7303 and ISO 15202 methods. Benefiting from our specialized Temperature & Humidity Controlled Weighing Chamber along with our precise microbalances, we also offer accredited gravimetric analysis of airborne particulate material on air filters to accurately quantify total particulate mass.
From gravimetric and metals analysis of air filters to measuring a wide range of organic compounds such as BTEX (Benzene, Toluene, Ethylbenzene, m,p-xylene, and o-xylene), VOCs (volatile organic compounds), and PAHs (polycyclic aromatic hydrocarbons) in ambient air — we’ve got you covered. We also specialize in syngas analysis and qualitative analysis of unknowns in ambient air and gas. You can trust our expert team in gas chromatography and industrial hygiene to provide you with a clearer understanding of what you’re breathing into your lungs!
Metals Analysis
Using our state-of-the-art ICP-OES and ICP-QQQ, we are capable of measuring a wide range of elements in MCE, Quartz Fiber, and PTFE air filter media.
