Topsil is Welch’s Next Generation Silica, with larger pore size and greater surface area, distinguishing Topsil stationary phases from those in our Ultisil Series.

Highlights

  • High purity silica (99.99%) with 150Å pore size and 250 m2/g surface area.
  • 12% carbon loading for C18 phase
  • Good for small molecules and peptides.
  • Lower back pressure than Ultisil®.
  • Because of large pore and moderate carbon loading, TopsilTM C18 phase can also be used at 100% aqueous condition without phase collapse.
