Welchrom Columns

Welchrom Columns

Welchrom uses the same purity(> 99.999% pure) Type B silica found in all Welch silica-based stationary phases. We combine it with bonding and endcapping steps exclusive to the Welchrom products to produce phases with slightly different selectivity than Ultisil or Topsil. 

Highlights

  • Excellent peak shape and low back pressure
  • Ultra high purity (>99.999%) Type B silica particles
  • New bonding and endcapping technique
  • Cost-effective
