WebMar 1, 1996 · Diode-Array based Peak purity determination by HPLC is a qualitative assessment of the impurity profile of the sample. It is designed to reveal impurities, not prove peak purity. WebMar 7, 2024 · To do so, the calibration solution was diluted till the respective values were reached. Selectivity (peak purity) of the separation was confirmed by symmetric peak shapes and consistent UV spectra throughout the peaks, which indicated that no co-elution or signal overlap occurred. Precision was evaluated both intra- and inter-day.
