Description
CHROMABOND Columns XTR, 70 mL, 14500 mg are solid-phase extraction columns filled with kieselguhr for supported liquid–liquid extraction in chromatographic sample preparation. Each unit provides a 70 mL column volume with a 14,5 g (14500 mg) kieselguhr bed, designed for aqueous sample volumes up to 20 mL. The polypropylene (PP) housing incorporates polyethylene (PE) filter elements to secure the sorbent bed during sample application and elution steps. These CHROMABOND XTR columns from manufacturer Macherey-Nagel support clean transfer of analytes from aqueous matrices onto a solid support before organic elution and subsequent analysis. They fit standard SPE manifolds and vacuum systems commonly used in analytical and research laboratories. Delivered as a pack of 30 pieces, the columns are suited to routine SPE sequences and higher sample loads. The PP body and PE frits offer chemical resistance compatible with typical extraction solvents, providing a reliable accessory for laboratories processing larger aqueous volumes in chromatography workflows.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns XTR, 70 mL, 14500 mg
What is this article?
Chromab. columns XTR, 70 mL, 14500 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.
