WebOne of the most useful diagnostics in HPLC is the nature of baseline produced by the detector whilst the eluent is flowing. While many baseline characteristics are common — such as drift, and atypical regulation cycling (pulsations) — baseline noise is arguably encountered more often and can arise from a variety of different sources. WebIf you are running and isocratic method baseline drift could be due to compounds strongly absorbed on the column that gradually elute. Try rinsing the column in a higher …
