HALO® Elevate – Taking Separations to a Higher Level
Built upon proven Fused-Core® particle technology for speed and efficiency, the HALO® Elevate C18 incorporates surface modified organo-silane technology for alkaline resistance resulting in excellent stability in high pH/high temperature environments.
With a wide operational use range of pH 2-12, HALO® Elevate allows for robust method development and improved separations for basic compounds that may present problems at lower pH, for poor peaks shapes, inadequate retention, or limited load tolerance. Ideal for use with high pH mobile phases, HALO® Elevate protects against degradation of the silica particle which is demonstrated by aggressive stability tests at elevated temperatures.
Available as a 120 Å pore size, these columns are optimized to deliver performance for high pH, to be flexible enough to work the full range of operating conditions to dial in separation selectivity for acids, bases, neutrals and zwitterions. The underlying HALO® Fused Core® technology is incorporated for separation speed and chromatographic efficiency to provide the quality HALO® has been known to exhibit.
