Our Indoor Air Quality (IAQ) group advises clients on indoor pollutants such as VOCs, fumes, odors, respirable dust and particulates.       MAS is capable of testing virtually any type of IAQ sampling media, including: SUMMA Canisters Stainless steel vessels which have had the internal surfaces specially passivated. MAS can provide canisters in sizes up to 15L. Sampling times can be varied from 2 seconds to 8 hours. Typically used for VOCs in ambient air.   Sorbent Tubes & Passive Organic Vapor Monitors Used in conjunction with sampling pumps that pull ambient air through the tube, sorbent tubes are typically used when analyzing for VOCs and SVOCs employing both solvent desorption and thermal desorption techniques for the analysis. Passive Organic Vapor Monitors are typically worn by workers throughout the day to measure chemical exposure levels.     MAS Uses the Latest Technology in Analytical Instrumentation Including: • Agilent GC and GCMS systems • Perkin Elmer Turbomatrix ATDs • Entech Sample Preconcentrator • Thermo-Finnegan HPLC • Dionix Ion Chromatograph • Perkin Elmer Flame Atomic Absorption Spectrophotometer • Jobin Yvon Inductively Coupled
