Description
CHROMABOND columns NH2/C18 are dual-phase solid-phase extraction columns combining an aminopropyl (NH2) layer with a C18 reversed-phase bed for selective sample clean-up and enrichment. Each polypropylene column has a 6 mL volume and is packed with 500 mg NH2 plus 1000 mg C18 sorbent, fitted with polyethylene filter elements to retain the bed during conditioning, loading and elution. The mixed-mode configuration supports polar and non-polar interactions in a single cartridge, which is useful when complex matrices require both ion-exchange/normal-phase and hydrophobic retention steps. Supplied in packs of 30 pieces from manufacturer Macherey-Nagel, these SPE columns integrate readily into manual or automated extraction workflows for environmental, food and pharmaceutical sample preparation. The robust PP housing and PE frits provide chemical resistance across common organic solvents and aqueous buffers used in chromatography laboratories. Designed as chromatography accessories, they help laboratories standardise dual-phase SPE protocols without assembling multi-cartridge sequences.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. col. NH2/C18, 6 mL, 500/1000 mg
What is this article?
Chromab. col. NH2/C18, 6 mL, 500/1000 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?
