Description
CHROMABOND HR-XA columns are solid-phase extraction columns featuring a strong mixed-mode anion exchanger on a polymer basis. Each unit combines a 3 mL reservoir with a 500 mg sorbent bed, a geometry widely used for selective clean-up and enrichment of anionic and acidic analytes in analytical sample preparation. The polypropylene body is fitted with polyethylene filter elements that secure the packing during conditioning, sample loading, washing and elution on vacuum manifolds or automated SPE systems. Offered as a pack of 30 pieces from manufacturer Macherey-Nagel, the columns support mixed-mode protocols in which ion-exchange and reversed-phase interactions work together to improve selectivity from complex matrices. Polymer-based mixed-mode phases of this type are valued in environmental, food and pharmaceutical laboratories for robust handling and straightforward method transfer. The 3 mL / 500 mg format balances capacity with solvent economy, making it practical for routine series as well as method development. Consistent hardware design helps laboratories maintain reproducible SPE workflows without changing manifold adapters or rack formats.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XA, 3 mL, 500 mg
What is this article?
Chromab. columns HR-XA, 3 mL, 500 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.
