Description
CHROMABOND Columns XTR, 45 mL, 8300 mg are solid-phase extraction columns packed with kieselguhr for supported liquid–liquid extraction in chromatography sample preparation. Each column offers a 45 mL bed volume with an 8300 mg kieselguhr fill, intended for aqueous sample volumes up to 10 mL. The column body is made of polypropylene (PP) and is fitted with polyethylene (PE) filter elements that retain the sorbent during loading and elution. These XTR columns from manufacturer Macherey-Nagel enable efficient transfer of analytes from aqueous matrices onto a solid support prior to organic elution and downstream chromatographic analysis. They integrate with standard SPE manifolds and vacuum processing setups used in analytical and research laboratories. Supplied as a pack of 30 pieces, the format suits routine batch work and method development. The inert PP housing and PE frits provide broad solvent compatibility for common extraction protocols, making the columns a practical accessory for laboratories handling aqueous samples in SPE workflows.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns XTR, 45 mL, 8300 mg
What is this article?
Chromab. columns XTR, 45 mL, 8300 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.
