High Quality Gas Generators for Gas Chromatographs

Oct 17 2008

Peak Scientific (UK) offers a range of Gas Generators specifically designed to supply Hydrogen, UHP Nitrogen and Zero Air to Gas Chromatographs. GCs can typically be operated with Helium, Nitrogen, Argon, Nitrogen and Air, but which gas to use is usually determined by the detector being used. Safety and availability can also influence the
selection of gases used for your analysis, e.g. high purity Helium can be difficult to obtain in some countries and gas bottles and cylinders pose a potential Health & Safety Hazard. The purity of the gases required is frequently determined by the detector, though the level of sensitivity needed can also play a significant role.
The gas flow rate affects the analysis in the same way that temperature does and the higher the flow rate the faster your analysis, but the lower the separation between the analytes. Selecting the flow rate is therefore the same compromise between the level of separation and length of analysis as selecting the column temperature. All this has
been considered when Peak Scientific developed their products. Their range of Hydrogen, Nitrogen and Zero Air Generators offer a safe and cost effective solution to your gas requirements whilst providing you with the purities and pressures required to operate your GCs. With different flow rates available the gas generators will provide you
with a suitable supply of laboratory gas for your specific application and all of Peak Scientific`s generators have been tried, tested & approved by leading instrument manufacturers.
