Description
CHROMABOND HR-XAW (45 µm) columns are solid-phase extraction columns based on a weak mixed-mode anion exchanger on a polymer matrix. The fine-grained sorbent has a particle size of 45 µm and is filled at 100 mg into a 1 mL column. Polypropylene bodies with polyethylene filter elements form a durable SPE housing for laboratory use. These columns from manufacturer Macherey-Nagel enable selective retention and clean-up of anionic and related analytes before chromatographic analysis. Mixed-mode polymer chemistry unites reversed-phase and weak anion-exchange mechanisms, giving flexibility when designing extraction methods for complex samples. Packs of 30 columns support method development, validation and routine SPE work in analytical environments. The 1 mL format with a 100 mg sorbent bed offers useful capacity for many small-volume applications while remaining easy to process on standard SPE equipment. As chromatography accessories, HR-XAW columns assist isolation of weakly acidic species and improvement of extract quality ahead of instrumental measurement, with 45 µm particles contributing to consistent packing characteristics in solid-phase extraction protocols.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

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