I am working on EPA 525.2 water analysis method using splitless mode ( Agilent 7890A GC). The problem I have is the reproducibility of the internal standards and surrogates. The peak shapes are all good but the peak areas could vary a lot. Can somebody working on the same method give me some guide? THanks
