Name: Gas chromatography / Liquid chromatography / Mass spectrometry
Model： 450GC/212LC/320MS
Place of Production： USA
Manufacturer： Varian Corp
Technology parameter：
1．scan range：GCMS：15~1050（m/z） ，LCMS：15~2000 （m/z）
2．sensitivity comes up to 10-15g
Instrument introduction：
The instrument equipment with four ion sources, GC/MS systems: Electron Ionization (EI) and Chemical Ionization (CI); LC/MS systems: Electrospray Ionization (ESI) and Atmospheric Chemical Ionization (APCI) .EI or CI would be most suitable for these smallest, least polar and most volatile molecules. Heavy, polar, and nonvolatile molecules are most suited for ESI and APCI.
Applications：
GCMS and LCMS can qualitative analysis or identify the unknown constituents present in a substance，it can be applied in many fields，such as organic synthesis，petrochemical，environmental and biomass products components.
