Varian has introduced the 325-MS triple-quadrupole LC/MS (liquid chromatograph/mass spectrometer) for detecting and identifying chemical compounds in high-throughput laboratories.
Analytical chemists face the challenge of identifying a growing list of compounds from an increasing number of samples in a variety of matrices.
Varian's 325-MS next-generation LC/MS triple-quadrupole mass spectrometer features a novel ESI ion source and improved ion-optics that enhance sensitivity, ruggedness and throughput.
At the heart of the 325-MS is Varian's VESI 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 analysing more compounds in a single run, increasing throughput and reducing the cost per analysis.
Gold-Guard ion optics enhance contamination resistance.
The 325-MS requires little cleaning to maintain a high-level of reproducibility and accuracy, even after repeated injections of analytes suspended in a complex matrix.
Fewer cleanings mean greater uptime and more productivity, again reducing the cost per analysis.
To help customers get the most from their instrument, Varian also provides consumables, including sample-preparation tools and HPLC columns, as well as applications assistance and a comprehensive selection of support and training options.
