Description
CHROMABOND columns SiOH-H2SO4/SA are dual-layer solid-phase extraction columns intended for demanding clean-up steps in analytical sample preparation. Each column has a 3 mL volume and contains 500/500 mg of the SiOH-H2SO4/SA sorbent combination, arranged to combine silica-based adsorption with strong acid functionality for targeted retention and matrix removal. The polypropylene housing includes polyethylene filter elements that maintain bed integrity and promote even solvent flow through conditioning, loading, wash and elution cycles. Supplied as a pack of 50 pieces from manufacturer Macherey-Nagel, the format fits common SPE manifolds and vacuum or positive-pressure systems used in routine laboratories. These CHROMABOND dual-bed columns support method development where sequential interaction mechanisms improve selectivity for complex environmental, food or chemical samples. Consistent fill weights help laboratories achieve reproducible recoveries across multi-sample batches. Handle and store according to the accompanying safety information for acid-containing SPE media.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. col.SiOH-H2SO4/SA,3mL,500/500mg
What is this article?
Chromab. col.SiOH-H2SO4/SA,3mL,500/500mg 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.
