Description
CHROMABOND HR-XAW columns (45 µm) combine a weak mixed-mode anion exchanger on a polymer basis with a fine 45 µm particle size. The sorbent is filled as a 200 mg bed in a 3 mL column, delivering higher capacity while retaining the fine-grained morphology useful for efficient mass transfer in SPE. Polypropylene column bodies with polyethylene filter elements secure the bed and support reliable flow during conditioning, sample loading, wash and elution. Available in packs of 30 pieces from manufacturer Macherey-Nagel, these HR-XAW columns sit within the CHROMABOND portfolio of chromatography accessories. The polymer-based weak mixed-mode anion-exchange chemistry is designed for selective handling of anionic analytes during laboratory sample preparation and clean-up. The 3 mL / 200 mg, 45 µm configuration suits workflows that need both elevated sorbent mass and fine particle characteristics, and it mounts readily on conventional SPE hardware used ahead of chromatographic analysis.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

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