I am using Scion GC-456 equipped with EVOQ MS/MS (Bruker), Column = Scion 5MS 15m x 0.25mm × 0.25 micron.
I used 10 minutes full scan mode for identification of pesticide standard (chlorpyrifos) peak but in this range no standard peak observed, now i want to increase scan time to 20 minutes, is it safe for EI to run continuously for 20-30 mins?
