Description
CHROMABOND HR-XA columns are solid-phase extraction columns based on a strong mixed-mode anion exchanger on a polymer support. They combine ion-exchange and reversed-phase retention to support selective clean-up and enrichment of anionic analytes in chromatography sample preparation. Each column offers a 1 mL volume with a 100 mg sorbent bed and is manufactured from polypropylene with polyethylene filter elements for stable flow and broad solvent compatibility. Available in packs of 30 pieces from manufacturer Macherey-Nagel, the HR-XA phase suits method development and routine SPE work with complex matrices in analytical laboratories. The polymer mixed-mode chemistry delivers robust selectivity where strong anion-exchange behaviour is required, for example in environmental, food and pharmaceutical workflows. Columns fit standard SPE manifolds and automated systems without special adapters. Consistent bed packing and PE frits help laboratories maintain reproducible recoveries in both manual and instrument-assisted protocols. This format is a practical choice for laboratories standardising mixed-mode anion-exchange SPE steps.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XA, 1 mL, 100 mg
What is this article?
Chromab. columns HR-XA, 1 mL, 100 mg 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.
