Peak Scientific hydrogen, nitrogen and zero air generators

Peak Scientific 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 analysis, eg, high-purity helium can be difficult to obtain in some countries and gas bottles and cylinders pose a potential health and 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 its products. The range of hydrogen, nitrogen and zero air generators offers a safe and cost-effective solution to a user’s gas requirements while providing the purities and pressures required to operate GCs.
