I am running samples on GC-FPD.
My calibration and sample peaks were all tailing so I was suggested to cut the end of the column from the detector and increase the carrier flow rate.
As I was cutting the column I noticed the detector inlet was not in the correct amount so I adjusted for that as well.
After cutting I ran my blank and did a bakeout. I have a total of 3 chromatographs (after column cut) and they all have an unidentified peak that was not present before.
Any suggestions on what I should do next?
