Some of the chromatogram errors that may arise if water impurities are present include tailing peaks, variable retention times, loss of resolution, negative peaks, baseline drift, adduct peaks, noisy baselines and spurious ghost peaks (see Figure 1).
However, by using same mobile phase on column ((ACE 5 C8), over an extended period, an extra peak (subsequently shown to be a diazepam degradant) was observed in the chromatogram just with baseline, resolved in front of the main diazepam peak (Fig 3b).
