not getting a signal

I am working on a Varian 3000. when I inject a sample I dont get any response the base line is very low( like 2mv) in til two min when it jumps up on 300mv. I am not sure where to go with this problem one thing i would like to do is see if the detector is working at all. Is there anyway besides doing a normal run that i could find out if it is working

bign007,

FID, TCD, NPD, what kind of detector under what conditions? The more info you provide, the more discussion you will get.

Best regards.
