- Novel API Interface and Ion Optics Improve Performance PALO ALTO,
Calif., Nov. 5 /PRNewswire/ -- 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. Gold-Guard(TM) ion optics (patent pending) provide
enhanced contamination resistance. The 325-MS requires little to no
cleaning in order 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. In order 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. "Maintaining and even
increasing throughput is essential for laboratories performing
environmental analyses and food safety testing," said Martin
O'Donoghue, Senior Vice President, Scientific Instruments, Varian,
Inc. "The 325-MS allows users to gather more information from each
run while spending less time maintaining the instrument." For more
