An anion column using hydroxide system ,characterized by large column capacity, high column efficiency, and high resolution of various ions. It can be used for the simultaneous separation of 7 kinds of conventional anions and SO32-,as well as for the analysis of small molecule organic acids and high concentration sample analysis(Cl-: NO2- concentration can reach 10000:1).
This column can achieve a good replacement for AS11-HC columns.
Suitable for simultaneous detection of conventional anions and sulfites;
The peak of carbonate is far away from sulfate, and high concentration of carbonate does not interfere with the determination of sulfate and other ions;
It can effectively separate the negative peaks of F- and water, while avoiding the interference of common organic acids such as acetic acid and formic acid in the detection of fluoride ions;
It is applicable to samples with high concentration difference. The concentration difference between chloride ion and nitrite ion can reach 10000: 1.
