Description
CHROMABOND SiOH columns with 3 mL volume and 500 mg sorbent fill are solid-phase extraction cartridges featuring an unmodified silica (SiOH) bed. The SiOH chemistry enables polar retention and normal-phase type clean-up during chromatographic sample preparation. Columns are manufactured from polypropylene (PP) and include polyethylene (PE) filter elements that keep the sorbent in place through conditioning, loading and elution steps. The 3 mL format with 500 mg fill balances sample capacity and solvent consumption for everyday SPE on vacuum manifolds or automated systems. Supplied in packs of 50 pieces from manufacturer Macherey-Nagel, they are well suited to medium-throughput laboratories that need a uniform mid-size silica cartridge. Defined volume and fill quantity support method transfer and batch-to-batch consistency. These CHROMABOND SiOH columns fit standard SPE hardware and are selected when a moderate-to-high silica load in a compact polypropylene housing is required for polar analyte work-up or matrix simplification before analysis.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns SiOH, 3 mL, 500 mg
What is this article?
Chromab. columns SiOH, 3 mL, 500 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.
