Description
CHROMABOND HR-XCW columns (45 µm) are solid-phase extraction columns fitted with a weak mixed-mode cation exchanger on a polymer basis. The fine-grained sorbent has a particle size of 45 µm and is packed at 200 mg per column in a 3 mL polypropylene body equipped with polyethylene filter elements. These SPE columns support selective retention and clean-up of cationic analytes in sample preparation workflows for chromatography. Supplied in packs of 30 pieces from manufacturer Macherey-Nagel, the format suits routine laboratory use where reproducible bed mass and defined particle size are required. The polymer-based mixed-mode chemistry combines weak cation-exchange functionality with reversed-phase character, enabling flexible method development for basic compounds from aqueous or organic matrices. Polypropylene hardware with PE frits provides chemical compatibility for common SPE solvents and buffers. Designed as chromatography accessories, the columns integrate readily into standard SPE manifolds and automated sample-preparation systems used in analytical and research laboratories.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XCW (45µm),3mL,200mg
What is this article?
Chromab. columns HR-XCW (45µm),3mL,200mg 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.
