VertiSep™ Anion AX1 column is packed with hydrophilic copolymer with quaternary ammonium functional group providing symmetrical peak shapes for inoganic and organic anions by both Suppressed and Nonsuppressed IC.
VertiSep™ Anion AX1 column is compatible with common mobile phases: p-hydroxybenzoate, sodium hydroxide, and sodium carbonate/bicarbonate. The p-hydroxybenzoate mobile phase is best used for bicarbonate and the seven common inorganic anions. Sodium hydroxide mobile phasweak acid anions
