Some 'bad' GC chromatograms
- > Tailing
- > Base line drift
- > 'Strange' baseline
- > Very sharp peaks on the baseline
- > 'Poor' peaks
- > Poor performance
- > Poor chromatogram
- > Injection problem? Doubling peaks
- > Injection problem
- > Disturbed baseline
- > Baseline drift
- > Poor peakshapes
- > Bad performance
- > 'Strange' baseline
- > 'Ghost peaks'
- > Negative peak
- > Poor peak shape. Buy new column?
