Description
CHROMABOND HR-XA columns are solid-phase extraction columns based on a strong mixed-mode anion exchanger on a polymer backbone. Each unit provides a 3 mL tube volume filled with 60 mg of sorbent, offering a compact bed for selective SPE of anionic and ionisable species. Column bodies are manufactured from polypropylene (PP) and fitted with polyethylene (PE) filter elements that retain the packing during solvent exchange and elution steps. Supplied in packs of 30 pieces from manufacturer Macherey-Nagel, these HR-XA columns belong to the CHROMABOND mixed-mode portfolio used in analytical sample preparation. The strong anion-exchange character on a polymeric support enables dual retention mechanisms—ionic interaction together with reversed-phase-type interactions—supporting clean-up of complex aqueous and biological matrices before HPLC or LC-MS analysis. Defined fill weight, PE frits and a 3 mL format allow straightforward use on standard SPE manifolds and automated systems. Consistent geometry across the pack helps laboratories maintain reproducible recoveries when transferring validated anion-exchange SPE methods between instruments and operators.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

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