Chromatography

Gas Chromatography (GC) – Agilent Technologies 7890B GC with Gas Sampling Valve (GSV)

Agilent 7890B Gas Chromatography with Gas Sampling Valve.

Agilent 7890B Gas Chromatography with Gas Sampling Valve

This customized Agilent 7890B Gas Chromatography system is equipped with a gas sampling valve at the inlet which is designed for direct gas sample tests. Two detectors, Thermal Conductivity Detector (TCD) at the back and Flame Ionization Detector (FID) at the front, are dedicated for detecting most permanent gases excluding the carrier gas and most organic compounds (e.g., hydrocarbons), respectively.
