Description
CHROMABOND HR-XA columns are strong mixed-mode anion exchangers on a polymer basis for solid-phase extraction and chromatographic sample preparation. Each unit offers a 6 mL volume packed with 150 mg of sorbent in a polypropylene housing equipped with polyethylene filter elements. The mixed-mode phase pairs anion-exchange functionality with hydrophobic interactions, supporting selective retention and clean-up of anionic analytes from demanding matrices. Available in packs of 30 pieces from manufacturer Macherey-Nagel, the columns are well suited to enrichment and fractionation ahead of HPLC, LC-MS or related analytical methods. The 6 mL / 150 mg configuration provides useful capacity while keeping solvent consumption practical for everyday laboratory use. Polymer construction together with PE frits promotes consistent flow and packing uniformity across the pack, aiding reproducible SPE performance in research and quality-control settings.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XA, 6 mL, 150 mg
What is this article?
Chromab. columns HR-XA, 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?
The category is SPE & sample preparation. The sub-category is SPE cartridges & columns. The catalogue is Chromatography equipment.
