Metrosep Organic Acids - 250/7.8

Metrosep Organic Acids - 250/7.8
Order number: 6.1005.200

The Metrosep Organic Acids - 250/7.8 is a polymer-based cation exchanger column. It is the high-performance column for the determination of organic acids and for the solution of difficult and complex separation problems. In addition, carbonate (with inverse suppression), fluoride (hydrofluoric acid) and phosphate (phosphoric acid) can be determined along with organic acids. In comparison with the Hamilton PRP-X300 - 250/4.0, the Metrosep Organic Acids - 250/7.8 has greater capacity and enhanced selectivity.
