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
