Description
CHROMABOND columns PS-MIX are solid-phase extraction columns combining mixed-mode polystyrene-based ion exchangers PS-H+ and PS-OH− for selective sample preparation in analytical laboratories. Each column offers a 3 mL volume with a 500 mg sorbent bed, housed in polypropylene with polyethylene filter elements to support reliable flow and retention during SPE workflows. Supplied in packs of 30 pieces from manufacturer Macherey-Nagel, these columns suit method development and routine clean-up where both cation- and anion-exchange interactions are required alongside hydrophobic contributions from the polymer matrix. The PS-MIX format helps laboratories handle complex matrices by enabling mixed-mode retention in a single cartridge geometry. Compact 3 mL barrels with a defined 500 mg fill support controlled loading and elution volumes typical of analytical SPE protocols. Use them for sample enrichment, matrix reduction, and preparation steps ahead of chromatographic or spectroscopic analysis where mixed-mode polymer phases are specified.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns PS-MIX, 3 mL, 500 mg
What is this article?
Chromab. columns PS-MIX, 3 mL, 500 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?
