Please help! I'm my lab we use analytical grade reagent IPA as our blanks. We have noticed that there are several peaks in the blank. It's getting very confusing with identifying which peaks are real and which are in the blank. The blank peaks are appearing on five different GCs which indicates to me it must be the solvent.
1. Has anyone else had issues with solvents seeming to be contaminated.
2. Does anyone have any idea what we could be doing wrong
