by Vertical Chromatography
VertiSep™ Anion AX300 column is packed with hydrophilic copolymer with quaternary ammonium functional groups providing symmetrical peak shapes for all anions by Suppressed IC.
VertiSep™ Anion AX300 column ideals for separation of 10 inorganic anions by suppressed IC using US EPA Method 300.1. The seven common anions (fluoride, chloride, bromide, nitrite, nitrate, sulfate, and phosphate), three oxyhalide anions (chlorite, chlorate, and bromate), and surrogate analyte anion (dichloroacetate) can be separated in one run.
VertiSep™ Anion AX300 column can also be used to determine inorganic anions in drinking water using US EPA Method 300.0 and trace bromate in drinking water using US EPA Method 317.0.
