Topsil Silica

by Welch Materials

  • High purity silica (99.99%) with 150 Å pore size and 250 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
  • Good for small molecules and peptides
  • Topsil phases including C18, C8, Phenyl and Silica
Application areas:
