Ultisil/Ultimate Columns

Ultisil/Ultimate Columns

Ultisil is a broad selection of various stationary phases, each one offering familiar separation behavior in its classification. Upgrade to Ultisil to make it easy to demonstrate equivalence with the phase you might be using currently – plus, you get the Welch Advantages of Purity, Chemistry and Consistency.

Highlights

  • Ultra-pure spherical porous silica, purity > 99.999%
  • Tested and proven low levels of trace metal contamination
  • Tenaciously-controlled bonding chemistry and end-capping
  • Class-leading reproducibility, efficiency, symmetry, and lifetime

P.S. The “Ultimate” series columns and “Ultisil” series columns are the same product with different names to meet our global marketing strategy. The P/N of an Ultisil column is the P/N of its Ultimate counterpart with a prefix "H".
