Chromatograms obtained during the optimization of the analytical method for the simultaneous determination of glycerol, sorbitol, and sucrose in pharmaceutical formulations

The content of each respective folder are: Folder “Analytes and some interferents”: Chromatograms of solutions containing the analytes and potential interferents; Folder “Variation of concentrations of NaOH and NaAc in eluent”: Chromatograms of a solution containing the analyte and propylene glycol (referred to as M4) obtained at different eluent concentrations, with each folder corresponding to a specific concentration; Folder “Eluent flow rate variation”: chromatograms of solution M4 obtained with different flow rate of the eluent; Folder “Injection loop volume variation”: chromatograms of solution M4 obtained with different injection loop volume; Folder “Column furnace temperature variation”: chromatograms of solution M4 obtained with different column furnace temperature; Folder “Calibration curve”: chromatograms of solutions of the analytes with concentration varying simultaneously from 0.001 to 0.300 g L⁻¹; Folder “Interferent analysis”: chromatograms of solutions of the analytes with and without possible interferent in a high concentration; Folder “Standard addition”: chromatograms of commercial samples (each displayed in a separate folder), both without and with standard addition, as well as chromatograms of standard solutions containing the respective analyte at concentrations ranging from 10 to 20 mg L⁻¹.
