by Vertical Chromatography
VertiSep™ Anion AX2 column is packed with hydrophilic copolymer with quaternary ammonium functional groups providing symmetrical peak shapes for all anions by Suppressed IC.
VertiSep™ Anion AX2 column is ideal for routine common anions analysis and for determining other strongly retained hydrophobic anions such as iodide, thiosulfate, and thiocyanate. Carbonate/bicarbonate gradients offer a powerful tool for separating anions that have a wide range of affinities for the column.
VertiSep™ Anion AX2 column can also be used to determine weak organic anions such as acetate and formate without the interference from fluoride and chloride.
