Tetrabutyl quaternary ammonium salts are phase transfer catalysts with superior performance. The tetrabutylammonium bisulfate buffer salt system is commonly used as the aqueous mobile phase in reverse phase liquid chromatography detection. However, the stability of the tetrabutylammonium bisulfate buffer salt system gradually decreases with the increase of tetrabutylammonium bisulfate concentration. The buffer salt solution of tetrabutylammonium bisulfate must be prepared before use and should not be used for more than 6 hours (obvious turbidity can be seen after being left at room temperature for 8 hours), otherwise it will cause chromatographic peak drift and even salt precipitation in the pump or chromatographic column, resulting in damage to the pump and chromatographic column.
