Abstract:The analysis method of bromamine acid was studied with RPIP HPLC. Chromatographic conditions are with methanol water was mobile phase, tetramethylammonium bromide as ion pair reagent, 2 naphthol as internal standard, and UV detection at 240nm. The method gives a linear range of O~0.18mg/mL and a coefficient of variation of 0.26%~0.81%. |
Key words:Bromamine acid; RPIP HPLC |
