Description
CHROMABOND columns HR-XCW (45 µm) are fine-particle, polymer-based solid-phase extraction columns with a weak mixed-mode cation exchanger for high-selectivity sample preparation. The 45 µm particle size provides a finer sorbent bed that supports efficient mass transfer while retaining the mixed-mode chemistry of cation exchange plus hydrophobic interaction on a polymeric backbone. Each column has a 3 mL volume and a 60 mg bed weight, manufactured from polypropylene with polyethylene filter elements for reliable flow and chemical resistance. Supplied in packs of 30 pieces from manufacturer Macherey-Nagel, these SPE columns suit clean-up and enrichment of basic analytes in demanding matrices. The fine-grained HR-XCW phase is well suited to pharmaceutical, environmental and food analytical methods where dual retention mechanisms improve selectivity over single-mode sorbents. Ready-to-use format allows direct use on vacuum manifolds or automated SPE systems, simplifying method transfer and routine laboratory workflows.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XCW (45 µm),3mL,60mg
What is this article?
Chromab. columns HR-XCW (45 µm),3mL,60mg 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?
The category is SPE & sample preparation. The sub-category is SPE cartridges & columns. The catalogue is Chromatography equipment.
