UN-C8

Sitting between the C4 and C18 members of the Uniformity family, UN-C8 columns give the HPLC Columns range a mid-retention reversed-phase option. Vintage Chrom Vintage Uniformity C8 is chosen by analysts who need C18-like selectivity with faster elution of hydrophobic compounds.

The 188 listings include 125 x 4 mm columns in 3 µm and 5 µm particle sizes, each on a 100 Å or 300 Å pore. That means a single chemistry can be specified for small-molecule assays on the 100 Å material and for peptide mapping or protein separations on the 300 Å material.

Use the 3 µm, 100 Å column for impurity methods that need plate count, the 5 µm version for routine content assays, and the wide-pore grades when analyte size approaches a few kilodaltons. Transfer between bores and lengths is straightforward because the surface chemistry stays the same. Lancetech Limited can quote any UN-C8 column.
