Description
CHROMABOND columns CN/SiOH are solid-phase extraction columns for chromatographic sample preparation. Each unit has a 6 mL reservoir and a dual sorbent bed of 500 mg cyanopropyl (CN) phase combined with 1000 mg unmodified silica (SiOH), enabling complementary polar interactions during clean-up and enrichment steps. The column body is polypropylene fitted with polyethylene filter elements, giving a robust, solvent-compatible format for vacuum manifolds or positive-pressure systems. This BIGpack presentation from manufacturer Macherey-Nagel supplies 250 columns, packed as five bags of 50 pieces, which suits routine high-throughput work and reduces reorder frequency. CN/SiOH dual-layer cartridges are widely used when polar to moderately polar analytes must be retained, fractionated or purified from complex matrices ahead of HPLC, GC or related techniques. The ready-to-use format integrates directly into standard SPE workflows without additional assembly. Consistent bed geometry and PE frits support reproducible flow and recovery across large sample series in pharmaceutical, environmental and food laboratories.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab.columnsCN/SIOH,6mL,500/1000mgBIG
What is this article?
Chromab.columnsCN/SIOH,6mL,500/1000mgBIG 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?
