Description
CHROMABOND XTR columns with 3 mL volume and 500 mg bed weight are solid-phase extraction columns packed with kieselguhr (diatomaceous earth) for aqueous sample volumes up to 0,5 mL. The column body is made of polypropylene and fitted with polyethylene filter elements to support reliable flow and retention during extraction and clean-up steps. These columns are intended for routine sample preparation ahead of chromatographic analysis, where kieselguhr-based XTR phases are used to handle liquid samples efficiently. Offered in a pack of 50 pieces from manufacturer Macherey-Nagel, the format suits laboratories that process multiple samples in parallel and need consistent column geometry and packing mass. The 3 mL / 500 mg configuration matches smaller working volumes while remaining compatible with standard SPE handling practices. Net weight of the pack is 0,25 kg. Use according to established CHROMABOND XTR protocols for your matrix and subsequent analytical method.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns XTR, 3 mL, 500 mg
What is this article?
Chromab. columns XTR, 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?
The category is SPE & sample preparation. The sub-category is SPE cartridges & columns. The catalogue is Chromatography equipment.
