Analysis of anions using a chemical suppressor

ICSpak made by Jasco is a suppressor for anion chromatography. The packing material whose sulfonic acid group is chemically bonded to styrene-divinylbenzene porous polymer is packed in the PEEK tube. Using this suppressor at anion chromatography, the background of eluent decreases, and the sample changes to ionpair with high equivalent conductivity. This suppressor can be used repeatedly by recycling and washing.

The more sensitive detection of nitrate ion and nitrite ion is enabled by using the UV detector, which is shown in this report using inert system and ICSpak.
