Description
CHROMABOND PSA columns, 3 mL with a 500 mg sorbent bed, are solid-phase extraction columns intended for selective sample clean-up in analytical chromatography. Each polypropylene cartridge is fitted with polyethylene filter elements and filled with PSA (primary secondary amine) phase, which is widely applied for polar matrix removal and multi-residue sample preparation. The 3 mL volume and 500 mg bed loading suit medium-capacity SPE steps prior to chromatographic analysis. Supplied in packs of 50 pieces from manufacturer Macherey-Nagel, the columns support high-throughput laboratory routines in food, environmental and life-science testing. PSA sorbents are commonly chosen to reduce organic acids, sugars and related interferences from complex extracts. The PP housing with PE frits withstands typical organic solvents used in SPE workflows. These CHROMABOND PSA columns integrate with standard SPE manifolds and vacuum systems for consistent, reproducible sample preparation.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

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