HPLC Separation of Bromoacetic and Chloroacetic Acids on Newcrom BH Column
High Performance Liquid Chromatography (HPLC) Method for Analysis of Difluoroacetic acid , Dichloroacetic acid , Dibromoacetic acid , Acetic Acid , Bromoacetic acid , Chloroacetic acid , Bromochloroacetic acid .
Acetic acid and its various chloro- and bromo- forms are widely used in organic chemistry. Their similar structure makes the acids difficult to retain and separate on reverse-phase HPLC columns. By using Newcrom BH mixed-mode column which also has ion-exchange properties, the separation can be achieved with a simple isocratic method and relatively short time with a mobile phase of acetonitrile (ACN), water and sulfuric acid (H2SO4) buffer. UV detection at 200 nm.
