I have been looking for information regarding the realistic consumption in GC, but didn't find something truly solid, especially regarding the flow variation betwing injection and pre/post injection phases.
The central idea is to build a calculator, with ajustable parameters, where people can evaluate their investment in different sources of gases.
Considering the two scenarios below, what would be the total gas flow per day for:
1 - Split injection; split ratio 20:1; collumn flow 2 mL/min; make-up 35 mL/min - Working sequential 20-minute runs during 12 hours and beeing in standy by 12 hours.
2 - Splitless injection: collumn flow 2mL/min; make-up 35 mL/min - Working sequential 20-minute runs during 12 hours and beeing in standy by 12 hours.
Please consider using the gas saver mode to minimize waste as much as possible.
Are there any significant points to consider? Please fell free to be as judicious as you want. The more thorough, the better!
