Alltech® Platinum™ Columns None

For Challenging Separations

  • Unique selectivity
  • Better peak shapes with polar analytes
  • More separation choices with dual-selectivity
  • Excellent stability and reproducibility
  • 1.5µm high throughput media for speed and resolution, especially when combined with Rocket™ and Expedite™ hardware

The Platinum™ Column Advantage

Controlled silica exposure is the difference that makes Platinum™ columns unique. Instead of thoroughly covering the silica with bonded phase to hide the silica, the exposure of the silica in Platinum™ columns is controlled to provide a dual mode separation with both polar and non-polar sites exposed to your samples. This extends polar selectivity well beyond what other reversed-phase columns offer and gives separations other columns cannot.

Standard Platinum™ Columns vs Platinum™ EPS Columns

Platinum™ columns come in two varieties offering different levels of silica exposure. Standard Platinum™ has a moderate silica exposure and is best used with neutral and moderately polar compounds. Platinum™ EPS (Extended Polar Selectivity) has a high level of silica exposure and is best used with compounds containing more than two polar functional groups.
