The Varian 920-LC is a fully automated, computer controlled analytical HPLC system that offers Fast LC capabilities, state of the art performance and improved productivity
When used with short, highly efficient Varian’s Pursuit XRs Ultra 2.8 and Pursuit UPS 2.4 HPLC columns packed with sub-3micron particles, chemists will be able to achieve shorter analysis times, better peak shapes (10-15% higher efficiency) and better quality data, says the company.
The 920-LC comprises a pumping system, an autosampler and one or more detectors.
The system is preconfigured, pre-plumbed and pre-tested before shipment, significantly reducing the time required to achieve maximum sample throughput.
A choice of built-in, programmable dual-wavelength or information-rich diode array (190-900nm) UV-vis detectors feature low noise and high sensitivity to deliver lower detection limits for trace analysis.
Optional fluorescence, refractive index, and evaporative light scattering detectors allow a wide variety of analyses to be performed with the 920-LC.
The new columns allow chromatographers to analyse samples faster while achieving higher resolution and reducing the cost per analysis.
Pursuit XRs Ultra 2.8 provides enhanced speed for virtually any HPLC instrument, allowing 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 3micron 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-2micron columns, and near equal efficiencies, Pursuit UPS 2.4 delivers better resolution and increased sensitivity at moderate flows and back pressures.
The Varian 940-LC is a dedicated analytical to semi-preparative (semi-prep) system.
It can be used both as an analytical HPLC and for scaling-up flows to work with larger capacity preparative scale columns to isolate, purify and collect moderate quantities of components of interest in a sample.
The 940-LC saves time and valuable sample material by allowing chromatographers to optimise their separations and collect purified components on the same instrument.
Offering analytical and semi-prep capabilities in a single instrument reduces the expense, maintenance, and complexity of employing separate systems.
The 940-LC automates the transition from analytical to semi-preparative flow rates without the need to change plumbing or configurations, reducing the possibility of errors and subsequent losses of potentially precious materials.
