Model 301-C Process Gas Chromatograph

Product information

  • The Model 301-C PGCs are flexible and versatile Analyzers that are in their fourth generation.
  • The addition of these new Analyzers greatly improves the capability and range of Process Analyzers from PID.
Model 301-C Process Gas Chromatograph



Photoionization detector (PID), Flame ionization detector (FID), Thermal conductivity detector (TCD), Flame photometric detector (FPD), Far UV absorbance (FUV) detector

Species measured

PID & FID: Organics (VOCs by PID or FID) and inorganic species (H2S, NH3, AsH3… ) that can be ionized by the PID lamp (9.5, 10.6 or 11.7 eV)
TCD: Universal detector- fixed gases (O2, N2, CO…), organic and inorganic compounds, very sensitive for H2, He, Xe
FPD: Selective response for S or P compounds
Far UV: Nearly universal response for organic and inorganic compounds
