My delta V seems to be pumping too good...In conflo I have 3 10-7 torr so my
signal for a 2 microliter of N2O (~100nmol) is only ~1 volt which seems about
an order of magnitude too low...This is after changing the inlet from 50
micron to 100 micron capillary. Ive cut ends off twice to ensure no blockage,
but still good vacuum. Is going to 200 micron an option anyone else has
tried?
