Description
CHROMABOND columns OH (Diol) are solid-phase extraction columns for chromatography sample preparation, each with a 3 mL bed volume and a 500 mg diol (OH) sorbent fill. The diol-bonded phase supports polar interactions useful in normal-phase and polar SPE workflows where hydrogen bonding and intermediate polarity retention are required. Column bodies are made of polypropylene (PP) and incorporate polyethylene (PE) filter elements that retain the sorbent during conditioning, sample loading, washing and elution on vacuum or positive-pressure manifolds. Offered as a pack of 50 pieces from manufacturer Macherey-Nagel, these columns form part of the CHROMABOND range of chromatography accessories for routine clean-up and enrichment steps ahead of analytical separation. The 3 mL format balances workable sample and solvent volumes with a compact footprint on multi-position SPE racks, while the 500 mg fill mass provides a defined bed for method transfer and day-to-day laboratory use. Consistent PP housing geometry and PE frits help maintain uniform packing support across the pack, supporting reproducible handling in high-throughput sample-preparation sequences.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns OH (Diol), 3 mL, 500 mg
What is this article?
Chromab. columns OH (Diol), 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?
