200 Series Gas Chromatograph

The 200 series compact gas chromatograph with its patented flow through technology is now well established at providing excellent chromatographic performance and reliability.

Each GC is a dedicated single channel unit with a split / split-less injector, programmable pressure control and a choice of three detector options. With either a flame ionisation, thermal conductivity, or electron capture detector the 200 series GC can cover most of the analytical applications in industry today. Manual or Automatic Gas sampling Valves can also be fitted to the 200 Series GC.
