Description
CHROMABOND HR-XAW columns are solid-phase extraction columns based on a weak mixed-mode anion exchanger on a polymer support. Each unit has a 6 mL column volume and a 150 mg sorbent bed, giving a practical format for selective sample clean-up and enrichment ahead of chromatographic analysis. The housing is polypropylene fitted with polyethylene filter elements that retain the packing during conditioning, loading, wash and elution steps. The mixed-mode polymer chemistry combines weak anion-exchange sites with reversed-phase character, enabling retention of anionic analytes together with hydrophobic interactions in a single SPE bed. Packs of 30 columns support method development and routine laboratory workflows on vacuum manifolds or automated SPE systems. These CHROMABOND HR-XAW columns from manufacturer Macherey-Nagel are intended for use as chromatography accessories where polymer-based mixed-mode anion exchange is required. The 6 mL / 150 mg configuration balances bed capacity with solvent use for typical laboratory sample volumes while remaining compatible with common organic solvents and aqueous buffers used in solid-phase extraction.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XAW, 6 mL, 150 mg
What is this article?
Chromab. columns HR-XAW, 6 mL, 150 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?
