Description
CHROMABOND columns HR-XCW are solid-phase extraction columns featuring a weak mixed-mode cation exchanger on a polymer basis. Each unit offers a 1 mL column volume filled with 30 mg of sorbent, giving a compact format for selective sample preparation in analytical laboratories. The housing is made of polypropylene and is equipped with polyethylene filter elements to support controlled flow through the bed. These CHROMABOND HR-XCW columns from manufacturer Macherey-Nagel belong to the chromatography accessories range and are intended for mixed-mode cation-exchange SPE workflows. The polymer-based weak cation-exchange chemistry combines hydrophobic interaction with cation-exchange retention, which is useful when basic or cationic analytes must be isolated or cleaned up from liquid matrices before chromatographic measurement. A pack contains 30 columns, suitable for method set-up as well as routine series work. The defined 1 mL geometry and 30 mg fill amount help keep bed mass consistent from column to column. Laboratories can integrate the columns into manual SPE manifolds or automated sample-preparation systems as part of broader HPLC or LC-MS sample clean-up schemes that rely on weak mixed-mode cation exchange.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XCW, 1 mL, 30 mg
What is this article?
Chromab. columns HR-XCW, 1 mL, 30 mg is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in SPE cartridges & columns, inside SPE & sample preparation, in Chromatography equipment.
An SPE cartridge holds a bed of sorbent. Bed mass, sorbent chemistry and volume are the specification. A 100 mg C18 cartridge and a 1 g C18 cartridge take different sample loads and different elution volumes. The method names all three.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
