Chromab. columns HR-XAW (45 µm),1mL,30mg

CHROMABOND HR-XAW (45 µm) columns are solid-phase extraction columns with a weak mixed-mode anion exchanger on a polymer basis. The fine-grained sorbent has a particle size of 45 µm and is packed at 30 mg in a 1 mL column format. Polypropylene housings with polyethylene filter elements give a practical SPE format for laboratory sample preparation. These columns from manufacturer Macherey-Nagel support selective retention and clean-up of anionic and related analytes ahead of chromatographic analysis. Polymer mixed-mode chemistry combines reversed-phase interactions with weak anion-exchange functionality, aiding flexible method design across varied matrices. Each pack contains 30 columns, suitable for method development, validation and routine SPE workflows in analytical and quality-control laboratories. The 1 mL geometry with a 30 mg bed mass fits small sample volumes and modest analyte loads while remaining convenient to handle on standard SPE manifolds. As chromatography accessories, HR-XAW columns help isolate weakly acidic target species and improve extract cleanliness before instrumental measurement, with consistent 45 µm particles supporting reproducible packing behaviour in SPE protocols.
