High Quality Gas Generators for Gas Chromatographs
Jun 22 2007
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. Our 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 our gas generators will provide you with the most suitable supply of laboratory gas for your specific application and all of Peak Scientific's generators have been tried, tested & approved by the world's leading Instrument Manufacturers.
