Description
CHROMABOND SiOH columns are solid-phase extraction columns designed for chromatography sample preparation in analytical laboratories. Each column offers a 3 mL volume and is packed with 200 mg of unmodified silica (SiOH) sorbent, suitable for normal-phase SPE workflows and polar analyte retention. The housing is manufactured from glass and fitted with a glass-fibre filter element to support reliable flow and sorbent retention during conditioning, loading, washing and elution steps. Supplied in packs of 50 pieces from manufacturer Macherey-Nagel, these columns fit routine laboratory SPE manifolds and vacuum or positive-pressure processing setups. Glass construction is advantageous when solvent compatibility or low extractables are preferred over standard polymer housings. Typical applications include clean-up and enrichment of extracts prior to HPLC, GC or other chromatographic analysis in environmental, food, pharmaceutical and research laboratories. The SiOH phase provides a well-established polar surface for method development and established SPE protocols requiring unmodified silica.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns SiOH, 3 mL, 200 mg, gl.
What is this article?
Chromab. columns SiOH, 3 mL, 200 mg, gl. 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?
