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

CHROMABOND columns HR-XCW (45 µm) are solid-phase extraction columns with a fine-grained weak mixed-mode cation exchanger on a polymer basis. The stated particle size is 45 µm, and each column provides a 1 mL volume filled with 30 mg of sorbent. Polypropylene housings with polyethylene filter elements complete the SPE format for laboratory sample preparation. Supplied by manufacturer Macherey-Nagel, these CHROMABOND HR-XCW fine-particle columns support mixed-mode cation-exchange clean-up of liquid samples prior to chromatographic analysis. The polymer-based weak cation-exchange phase combines reversed-phase character with cation-exchange interaction, which is relevant when cationic or basic target compounds must be retained and released under controlled conditions. Packs of 30 columns allow consistent use in method development and routine SPE sequences. The 1 mL bed geometry with a 30 mg fill amount and 45 µm particles offers a defined fine-particle option within the HR-XCW range. Chromatography laboratories can place the columns on manual manifolds or automated SPE platforms as part of sample-preparation workflows that depend on weak mixed-mode cation-exchange selectivity.
