AX/S Extraction Columns, 4 mL

XTRX Extraction Columns were designed and intended for use in the extraction of analytes from aqueous samples, such as urine, serum and environmental samples, as well as process stream using the DuPont Prep 1 Automated Sample Processor, the XTRX 4 Sample Processor, or a vacuum box.

Extraction columns are supplied with a cap, waste cup, and sample recovery cup. The columns contain water and a nominal 120mg of a polymeric strong anion exchange resin retained by a porous filter. The column reservoir will hold approx. 4ml of sample. The waste cup has a capacity of approx. 6ml and is used to collect liquid (normally waste) passed through the column when the rotor is spinning in a clockwise direction.

The sample recovery cup has a capacity of 4ml and is used to collect the sample when rotor is rotating in a counterclockwise direction. The sample components are released from the resin by the use of an acidic eluting solvent and collected in the sample recovery cup.
