Grace: Prevail

Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.

  

The general features of Prevail include:

  • Stable from highly organic to highly aqueous
  • Speciality phases for specific applications
  • Excellent sensitivity with microbore and ELSD applications

Prevail Organic Acid (OA) columns:

are silica-based for maximum efficiency and high resolution. They can separate common organic acids with a combination of speed, sensitivity and simplicity. A simple acidic phosphate buffer and a Prevail OA column at ambient temperature will separate 11 short chain organic acids in less than 6 minutes. Column selectivity can be readily adjusted by changing pH.
