High quality Tetrabutylammonium bromide / TBAB with best price 1643-19-21

When using liquid chromatography to analyze samples with strong ionization ability, if the retention time of the sample on the reverse phase chromatography column is very short or not retained at all, corresponding ion pair reagents should be added to bind the ions on the analyte and form molecules with retention on the column. Tetra-n-butylammonium bromide, Cas:1643-19-2 is one of the ion pair reagents. According to relevant studies, its impact on separation efficiency is that as the concentration of ions in the mobile phase increases in the reagent - Tetrabutylammonium bromide(TBAB),Cas:1643-19-2, the retention value of anions increases, and the separation degree between anions and coexisting ions also increases. When the concentration of tetrabutylammonium bromide Cas No.:1643-19-2 is greater than or equal to a certain degree, baseline separation can be achieved between anions and other coexisting ions. In addition, within a certain range of further increase in the concentration of Tetrabutylammonium bromide, the anion peak area remained basically unchanged.
