ANIONS: IC columns used with chemical suppression

The A Supp 3 –250 solves separating problems in aqueous and organic media. It can be used reliably with a wide range of eluents - even those containing large amounts of organic solvents. With the A Supp 3 – 250 samples that represent a great analytical challenge can be analyzed routinely, for example biological samples or inorganic anions in organic matrices. Polyphosphates may be separated on the Metrosep A Supp 3 – 250 by applying a sodium hydroxide gradient. The column is also suitable for the separation of sulfite, sulfate and thiosulfate in less than 20 min.
