Development of an Ion Pairing Reagent and HPLC UV Method

2.3. Standard Preparation. The six vitamins were classified into three groups, groups 1, 2, and 3, and stock solutions were prepared using the preprocessing reagent, water, and 0.01 N NaOH to obtain a final vitamin concentration of 100 mg/L. Group 1 consisted of thiamine and pyridoxine, and the stock solutions were prepared by mixing the standard preparation with water (100 mL).
