Pursuit XRs Ultra 2.8 provides enhanced speed for virtually any HPLC instrument. Optimized 2.8 micron silica particles allow chemists to increase flow rates and use a wide range of mobile phases without going above the maximum operating pressure of the instrument. . At the same time, it delivers better resolution (10-15% higher efficiency) than typical 3 micron columns. Users can get high speed performance from conventional LC systems, avoiding the need to invest in new equipment.

Pursuit UPS 2.4 columns are designed to provide improved performance on standard 'low dead-volume' HPLC systems without the need for ultra-high pressures. With approximately 50% lower back pressure than sub-2 micron columns, and near equal efficiencies, Pursuit UPS 2.4 delivers better resolution and increased sensitivity at moderate flows and back pressures. Now, analytical chemists can achieve "Fast LC" with HPLC and LC/MS systems at a fraction of the cost of ultra-high pressure systems.
