Welchrom uses the same UHP (> 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
