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
