I appreciate there have been many discussions about this, as this is an issue for many of us, but I am wondering whether any of you use Helium grade A as GC carrier.
We are currently using CP grade with O2/moisture scrubbers (Agilent Gas Clean). Our lab uses GC-FID to analyse congeners in whisky samples on a CP-Wax column. Our current detection limit is around 0.1g/100L. I am thinking about ways to keep using Helium as carrier but reduce costs and improve supply.
Thank you!
