Helium is still the preferred carrier gas for many GC-MS methods.
But keeping a GC-MS on helium all day is becoming harder to justify.
For many laboratories, the instrument may only be actively running part of the day, while helium continues to be consumed during standby.
With helium prices under pressure and supply uncertainty still a concern, that standby consumption adds up.
EXPEC is introducing an optional Helium Saving Module for the EXPEC 3700 and EXPEC 3750 GC-MS platforms.
The module works with the instrument’s digital EPC gas-control system to automatically switch the carrier gas from high-purity helium to high-purity nitrogen during idle periods, reducing unnecessary helium consumption without changing the normal analytical workflow.
In a typical scenario with 8 hours of operation and 16 hours of standby per day, combining the carrier-gas saving mode with the helium-saving module can:
reduce annual helium cost by more than 85%
extend the use time of one helium cylinder by more than 7×
reduce cylinder changes and dependence on helium supply
For routine GC-MS laboratories, the value is straightforward:
Use helium when the method needs it.
Do not waste it when the instrument is waiting.
Compatible with EXPEC 3700 / EXPEC 3750 GC-MS.
