LC Columns speed analysis times on HPLC systems.

Press Release Summary:



Pursuit XRs Ultra 2.8 columns feature micron silica particles, allowing chemists to increase flow rates and use wide range of mobile phases without going above maximum operating pressure of instrument. Pursuit UPS 2.4 columns are designed for standard low dead-volume HPLC systems without need for ultra-high pressures. Fast LC columns target analytical chemists in pharmaceutical/environmental laboratories for separation, identification, and quantification of sample components.

New Liquid Chromatography Columns from Varian, Inc. Reduce Analysis Times on Standard HPLC Systems



PALO ALTO, Calif., Jan. 7 / / -- Varian, Inc. (NasdaqGS: VARI) announced today that it has launched its new family of Pursuit(TM) "Fast LC" columns for high performance liquid chromatography with Pursuit XRs Ultra 2.8 and Pursuit UPS 2.4. These new columns allow chromatographers to analyze samples faster while achieving higher resolution and reducing the cost per analysis. Both columns are intended for use by analytical chemists in pharmaceutical and environmental laboratories for the separation, identification and quantification of sample components.

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.

"Reducing the time needed to analyze a sample can result in significant savings for laboratories that run hundreds of samples per day," said Martin O'Donoghue, Senior Vice President, Scientific Instruments, Varian, Inc. "Varian's new Pursuit XRs columns have put those savings within the reach of our customers without the need for capital investment."
