The Thermo Scientific TVA-1000B Toxic Vapor Analyzer is capable of measuring a variety of organic vapors using FID technology, over a wide range of organic vapors can be measured, by the FID, over a wide dynamic range (0-50,000 ppm), monitoring some compounds that PID will not detect. The FID operates by breaking hydrocarbon bonds and is not limited by a high ionization potential of the molecule. In addition, the FID is unaffected by ambient CO, CO2 , or humidity leading to very stable measurements.
