Abstract
The data presented are related to the article entitled "Six Sigma quality approach for HPLC-UV method optimization" Ibrahim et al., 2019. The raw data of HPLC analysis of ascorbic acid (AS), paracetamol (PA) and guaifenesin (GU) are presented. Calibration standards were prepared at six concentrations levels (25%, 50%, 75%, 100%, 125% and 150%) each day and measured in triplicate. Validation standards were prepared at four concentration levels (25%, 60%, 100% and 150%) each day and measured in quintet. Three different series were used for method validation and prepared at the rate of one series per day.
