Helium Save Option for GC and GC-MS
Helium - EcoSaver
Helium is a rare noble gas that can only be obtained from helium-containing natural gas sources in a few places on earth.
To reduce the consumption of increasingly scarce and therefore more expensive helium, CHROMTECH has developed the Helium EcoSaver option for GC and GC-MS systems. When using this system, only helium is consumed when it is actually needed, during a measurement, or during a sample sequence. Thereafter, the carrier gas supply is automatically switched to a different gas, eg. nitrogen. The switch to measurement mode with helium is either automatic, by starting a measurement or sequence, or manually by pressing a button on the control unit. In either case, after switching the carrier gas type, a purge time set by the user enables flushing out residues of e.g. nitrogen from the chromatographic system. Only then does the measurement or sample series start.
This can be part of a method for Agilent GC or GC/MS systems and also supports previous Agilent GC models. For other GC brands the carrier gas switch is performed by pressing a button on the unit.
