Description
CHROMABOND HR-XA columns (45 µm) are fine-grained solid-phase extraction columns with a strong mixed-mode anion exchanger on a polymer basis. The 45 µm particle size supports efficient mass transfer and selective retention of anionic analytes through combined ion-exchange and reversed-phase mechanisms. Each unit provides a 1 mL column volume filled with 100 mg sorbent and is built from polypropylene with polyethylene filter elements for reliable flow characteristics. Supplied in packs of 30 pieces from manufacturer Macherey-Nagel, this fine-particle HR-XA format is intended for demanding SPE clean-up and enrichment steps in analytical laboratories. Polymer mixed-mode chemistry offers robust performance across diverse sample matrices where strong anion-exchange selectivity is needed. The columns integrate with common SPE manifolds and automated platforms used in environmental, food and pharmaceutical analysis. Consistent packing of the fine sorbent bed and PE frits support reproducible recoveries in manual and instrument-assisted methods. Laboratories seeking finer particle SPE media for mixed-mode anion exchange will find this configuration a practical working format.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XA (45 µm),1mL,100mg
What is this article?
Chromab. columns HR-XA (45 µm),1mL,100mg 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?
