Description: The PID technique uses a lamp with known photon energies in the vacuum ultraviolet (VUV) region. The output from the lamp is used to photoionized gaseous molecules with ionization ...

User can configure the Thermo Scientific™ TVA2020 Toxic Vapor Analyzer as an FID analyzer (flame ionization detector), or as a PID analyzer (photo ionization detector) and dual-detection FID analyzer.
