Description
Chromafix HR-XAW (M) solid phase extraction cartridges are polymer-based weak mixed-mode anion exchangers intended for selective sample clean-up and enrichment in analytical laboratories. The medium (M) format provides a minimum sorbent bed of 120 mg, supporting retention of anionic and acidic target compounds through combined hydrophobic and weak anion-exchange interactions. These CHROMAFIX cartridges from manufacturer Macherey-Nagel are supplied as a pack of 50 pieces and fit routine SPE workflows used ahead of chromatographic analysis. The polymer backbone offers a robust mixed-mode phase for method development and reproducible batch processing of complex matrices in environmental, food, or pharmaceutical sample preparation. HR-XAW chemistry is chosen when controlled elution of weakly retained anions is required without relying solely on reversed-phase mechanisms. Compact cartridge handling simplifies conditioning, loading, washing, and elution steps on standard SPE manifolds. This configuration suits laboratories that need consistent polymer mixed-mode anion exchange performance in a convenient multi-piece pack for everyday chromatography accessory use.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromafix HR-XAW (M)
What is this article?
Chromafix HR-XAW (M) 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?
