Description
CHROMABOND Columns XTR, 70 mL, 14500 mg BIG pack are solid-phase extraction columns packed with kieselguhr for supported liquid–liquid extraction in chromatography sample preparation. Each column has a 70 mL volume and a 14500 mg kieselguhr fill for processing aqueous samples on a solid support. The polypropylene (PP) column body is equipped with polyethylene (PE) filter elements that retain the sorbent during loading and elution. This BIG pack format from manufacturer Macherey-Nagel contains 100 columns, packed in 20 bags of 5 pieces, supporting high-throughput SPE work and stock replenishment in busy laboratories. The XTR design enables efficient analyte transfer from aqueous matrices prior to organic elution and chromatographic analysis, and the columns are compatible with standard SPE manifolds and vacuum processing setups. The inert PP housing and PE frits provide solvent compatibility for common extraction protocols. This bulk configuration is intended for laboratories that require larger quantities of identical 70 mL XTR columns for routine sample preparation workflows.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

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