Switch to N2 carrier gas
Current practices:
He carrier gas, backpressure-regulated GC's (Agilent). A decent amount of work is injecting neat solvents for purity, use 400:1 split ratio to prevent overload. He is limited by EPC to a total flow of 1250mL/min.
Challenge:
N2 is limited by EPC to a total flow of 200mL/min. The 400:1 split ratio isn't possible.
Any suggestions?
