Description

Gas chromatograph/mass spectrometer intended for high-precision GC/MS qualitative analysis or identification of unknown compounds.

Specification

  • Helium is required as carrier gas with purity 99,995% or greater and pressure 300-980 kPa
  • Oven temperature: maximum 450oC
  • Injection port temperature: maximum 450oC
  • Linear temperature elevation rate:
