MNPK-C18

MNPK-C18 covers the Vintage Chrom Minipak C18 reversed-phase HPLC columns. Laboratories running legacy methods on 3.9 mm bore columns, as well as those on standard 4.6 mm hardware, use this range for everyday C18 assays of pharmaceuticals, additives and environmental samples.

The 68 listings are built on 125 Å pore silica bonded with C18, in 5 µm and 10 µm particle sizes. Sample formats include 125 × 4.6 mm and 125 × 3.9 mm columns, the latter a direct fit for older method specifications that call for a 3.9 mm internal diameter. The 125 Å pore sits between conventional small-molecule and wide-pore materials, giving useful retention for mid-sized analytes.

Choose the 5 µm packing for analytical resolution and the 10 µm packing for lower back pressure or higher loading. Keep the bore identical when reproducing a validated method. For a Minipak C18 quotation or a word on compatibility, contact Lancetech Limited.
