Hi Everyone,

My name is Harsha. I am a PhD student in university of antwerp, belgium.


I connected ESI source to LTQ XL mass spectrometer. To construct the method, I should not to use Sheath gas.
When i turn off sheath gas flow. The instrument (mass spec) is going to stand by mode and an error message pops up saying that sheath gas flow is less than minimum.
Is there a way that the instrument is ONN without sheath gas flow by having an ESI source.
