The GC is a Varian 3800 connected to a Star workstation in a network. The problem is that the chromatogram baseline remains very high after the first peak. As a result subsequent peaks are not well defined and difficult to determine.
Normally, the baseline should return to zero after each peak, allowing the peaks to be clearly defined.
Any ideas on what might be the cause, and the solution?
