Description
Polyamide for column chromatography is a polymeric stationary-phase material supplied for laboratory separation and purification work. This grade is intended for column chromatography and is characterised by a density of 1,14 g/cm³, with CAS number 25038-54-4. It is Polyamide media are selected when polar interactions, including hydrogen bonding, contribute to retention during fractionation of organic mixtures, natural-product extracts or synthetic intermediates. The material from manufacturer Carl ROTH fits classical open-column and low-pressure chromatography setups used alongside other stationary phases. Laboratories can dispense the polymer as required for slurry or dry packing according to their own protocols. Within polymer and chromatography applications, this polyamide serves as a dedicated medium where polyamide-based selectivity is required.

Questions about Polyamide, for column chromatography, 250 g, plastic
What is this article?
Polyamide, for column chromatography, 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Sorbents, silica gel & ion exchangers, inside SPE & sample preparation, in Chromatography equipment.
Loose sorbent, silica gel and ion-exchange resin are the phases bought in bulk to pack a column or to stir into a solution. Particle size and activity, or the ion-exchange capacity, are the specification. A TLC silica and a flash silica of different particle sizes are not the same separation.
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.
