I need some real expert's help.
I have Agilent GC 7890A. Water Quattro GC MS and CTC sampler.
Under the same conditions when I inject 1 uL the peak area was 3000 and when I inject 1.5 uL the peak area 15000(yes, 15000). I have a splitless liner(900uL). I tried both 265 C and 310 C inlet temperature; and 250 and 310 source and interface temperature. I am using SIR (209.2 for this trichloroanisole)
Sample is trichloroanisole 100pg/uL in acetone.
If you know possible reason please let me know.
