The Infon HAPSITE ER is a portable GC (Gas Chromatograph) / MS (Mass Spectrometer) that requires minimal training to measure qualitative and quantitative lab-grade results in less than 10 minutes. Users can easily identify volatile organic compounds (VOCs), toxic industrial compounds (TIC), toxic industrial materials (TIM), chemical warfare agents (CWA) and semi-volatile organic compounds (SVOC). Measurements can be taken in the ranges of ppm to ppb. Applications include environmental assessment, chemical monitoring and emergency response.
