Welch Materials Topsil C18 Columns

Topsil C18 offers distinct selectivity compared to other C18 columns from Welch Materials. With lower column pressure and higher efficiency, it is an economical HPLC column choice.

Topsil series HPLC column is a next-generation column by Welch, besides Ultisil, Xtimate and Welchrom. This series use different silica and provide different selectivity.

Features

High purity silica (99.99%) with 150 Å pore size and 260 m2/g surface area
12% carbon loading for C18 phase
Because of large pore and moderate carbon loading, Topsil C18 phase can also be used as AQ-C18 without phase collapse
Endcapped for excellent peak shape and lifetime
Lower back pressure than Ultisil, almost the same column efficiency as Ultisil columns
Good for small molecules and peptides
Topsil phases including C18, C8, Phenyl-Hexyl, Silica, NH2, HILIC NH2 and CN
