Description
CHROMABOND columns NH2/C18 are ready-to-use solid-phase extraction columns combining an amino (NH2) phase with a C18 phase in a dual-bed configuration. Each unit offers a 6 mL column volume filled with 500 mg NH2 and 500 mg C18 sorbent, giving a defined 500/500 mg bed for sequential or mixed-mode sample clean-up. The housing is polypropylene with polyethylene filter elements, a standard laboratory construction for SPE work under gravity, vacuum or positive-pressure manifolds. Supplied in packs of 30 pieces, the columns support parallel processing in food, environmental and general analytical laboratories that require amino and reversed-phase interactions in one cartridge. This CHROMABOND format from manufacturer Macherey-Nagel fits routine SPE workflows where dual-phase selectivity is specified in the method. The fixed bed masses and 6 mL geometry simplify method transfer and documentation compared with self-packed columns. Use according to your validated extraction protocol for matrices that benefit from combined polar and non-polar retention before chromatographic analysis.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

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