Description
CHROMABOND columns XTR, 70 mL, 17 g are solid-phase extraction columns for sample preparation in analytical laboratories. Each column holds a 17 g bed of diatomaceous earth (kieselguhr) in a 70 mL polypropylene body fitted with polyethylene filter elements, giving high sorbent capacity for aqueous clean-up and supported liquid–liquid extraction workflows. The ready-to-use format suits environmental, food and pharmaceutical matrices where larger sample volumes or higher loading are required before chromatographic analysis. Columns from manufacturer Macherey-Nagel can be mounted on standard SPE manifolds or vacuum systems, avoiding manual packing and supporting reproducible bed geometry from run to run. Polypropylene housings with PE frits offer broad chemical compatibility with common organic solvents and aqueous buffers used in routine SPE protocols. Supplied as a pack of 30 pieces, this XTR configuration is a practical choice when laboratories need consistent kieselguhr-based extraction capacity in a larger column format.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns XTR, 70 mL, 17 g
What is this article?
Chromab. columns XTR, 70 mL, 17 g 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.
