Description
CHROMABOND XTR columns with 30 mL volume and 4500 mg bed weight are solid-phase extraction columns packed with kieselguhr (diatomaceous earth) for aqueous sample volumes up to 5 mL. Each column uses a polypropylene body with polyethylene filter elements to provide stable flow and retention during extraction and sample clean-up. The larger 30 mL / 4500 mg format is suited to higher sample loads while remaining within standard SPE handling workflows for chromatographic sample preparation. Supplied in packs of 30 pieces from manufacturer Macherey-Nagel, these columns support laboratories that need reproducible packing mass and column geometry for multi-sample series. Kieselguhr-based XTR phases are widely applied when liquid samples must be processed efficiently before analysis. Net weight of the pack is 0,56 kg. Select this size when working volumes approach the upper range indicated for the XTR bed and follow established CHROMABOND XTR procedures for your matrix and method.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns XTR, 30 mL, 4500 mg
What is this article?
Chromab. columns XTR, 30 mL, 4500 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?
