Varian, Inc. (NasdaqGS: VARI) announced today the release of the 325-MS triple-quadrupole LC/MS (liquid chromatograph/mass spectrometer) for the efficient detection and identification of chemical compounds in high-throughput laboratories performing environmental, food safety, and toxicology analyses.
Analytical chemists face the challenge of identifying a growing list of compounds from an increasing number of samples in a variety of matrices. To remain competitive, laboratories must maximize the number of compounds they can detect and quantify in a single analytical run while minimizing the time spent on maintaining the instrument. The 325-MS, Varian's next generation LC/MS triple-quadrupole mass spectrometer features a novel ESI ion source and improved ion-optics that jointly enhance sensitivity, ruggedness and throughput.
At the heart of the 325-MS is Varian's patent pending vESI(TM) ion source, a vortex ESI ion source that improves sensitivity by increasing the efficiency of the desolvation process. A vortex of drying-gas facilitates ion desolvation at lower temperatures, accommodating a wider range of flow-rates for small molecule analysis as well as biomolecules without compromising system performance. Chemists can take advantage of the improved sensitivity by either lower detection limits for some compounds or by analyzing more compounds in a single run, increasing throughput and reducing the cost per analysis.
