Description
CHROMABOND HR-XA columns (45 µm) are solid-phase extraction columns that use a strong mixed-mode anion exchanger on a polymer support. Fine-grained 45 µm particles are packed as a 200 mg bed in a 3 mL polypropylene cartridge with polyethylene filter elements, combining higher sorbent capacity with the efficiency of a smaller particle size.
This article is part of SPE cartridges & columns, in SPE & sample preparation.
The mixed-mode polymer phase delivers anion-exchange selectivity together with reversed-phase character, which helps retain and clean up ionic and polar compounds from complex samples prior to chromatographic measurement. The 3 mL format integrates easily into manifold-based or automated SPE procedures, while the 45 µm grade supports effective mass transfer during conditioning, sample loading and elution.
Each pack comprises 30 columns from manufacturer Macherey-Nagel for laboratory sample preparation. The PP housing and PE frits are suited to typical aqueous and organic SPE solvent systems. With a 200 mg fill in the fine-particle HR-XA chemistry, these columns address applications that need both capacity and mixed-mode anion-exchange performance in a compact 3 mL SPE format.

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