Description
CHROMABOND HR-XA columns with 45 µm particles are fine-grained solid-phase extraction columns that combine a strong mixed-mode anion exchanger with a polymer base. The specified 45 µm particle size supports efficient mass transfer and reproducible flow characteristics in the 1 mL column format filled with 30 mg of sorbent. Polypropylene bodies equipped with polyethylene filter elements hold the polymer phase securely during conditioning, sample application, wash and elution sequences. Packaged as 30 pieces per unit, the columns are intended for laboratory SPE work that benefits from mixed-mode anion-exchange selectivity together with a finer particle bed. The HR-XA chemistry unites hydrophobic and strong anion-exchange retention mechanisms, which is useful for isolating acidic target compounds from complex matrices before chromatographic determination. These 45 µm CHROMABOND HR-XA 1 mL / 30 mg columns from manufacturer Macherey-Nagel fit conventional SPE hardware and automated extraction platforms used in method development and routine sample preparation.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XA (45 µm), 1mL,30mg
What is this article?
Chromab. columns HR-XA (45 µm), 1mL,30mg 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?
