XTRX Extraction Column, Type AX, 4mL (100/case) S11-51

APPLICATION 

Type AX extraction columns are intended for the use in the extraction of analytes from aqueous samples, i.e. environmental sample, urine, serum and process stream using the Dupont Prep™ 1 Automated Sample Processor, the XTRX™ 4 Sample Processor, or a vacuum box.

SUMMARY 

The concept of solid phase extraction has been applied to a broad range of materials including drugs of abuse, drug metabolites and steroids, and environmental pollutants.

Extraction columns are supplied with a cap, waste cup, and sample recovery cup. The columns contain 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.

For use with the XTRX-4 automated processor
