Gas chromatograph/mass spectrometer intended for high-precision GC/MS qualitative analysis or identification of unknown compounds.
- 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:
- 70oC/min up to 200oC
- 50oC/min up to 300oC
- 30oC/min up to 400oC
- Three-dimentional spectral data can be obtained, what allows the identification of components using library of spectra (private or public)
