Loss of Sensitivity on Varian Saturn 2200
Posted: Sat Sep 26, 2009 7:34 am
I have a saturn 2200. I have recently noticed that the peak areas for standards (oc pesticides and op pesticides etc) have reduced 3-4 times over the past 3-4 months. I am not sure why this is happening, could be that the column life is over?, but the separation of a standard oc or op mix on the column seems to be fine, i have also tried making fresh standards, but to no effect
