Description
CHROMABOND HR-XA columns (45 µm) are solid-phase extraction columns based on a strong mixed-mode anion exchanger on a polymer support. The fine-grained 45 µm particles are packed at a 60 mg bed mass in a 3 mL polypropylene cartridge fitted with polyethylene filter elements, supporting controlled flow and reproducible retention of anionic analytes.
This article is part of SPE cartridges & columns, in SPE & sample preparation.
Designed for sample preparation and clean-up in analytical chromatography workflows, the mixed-mode polymer phase combines ion-exchange selectivity with reversed-phase interactions, which is useful when polar and ionic species must be enriched or separated from complex matrices. The 3 mL format suits routine SPE protocols on manifolds or automated systems, while the fine particle grade favours efficient mass transfer during loading, washing and elution steps.
Each pack contains 30 columns from manufacturer Macherey-Nagel, ready for laboratory use in method development and routine analysis. The polypropylene housing with PE frits offers chemical resistance compatible with common aqueous and organic SPE solvents. These HR-XA units provide a practical format for laboratories that require consistent mixed-mode anion-exchange performance in a compact 60 mg / 3 mL configuration.

Questions about Chromab. columns HR-XA (45 µm), 3mL,60mg
What is this article?
Chromab. columns HR-XA (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.
