Varian last week launched the 325-MS triple-quadrupole LC-MS for the high-throughput detection and identification of chemical compounds.
The instrument is Varian's next-generation LC-MS triple-quad mass spectrometer and features the company's vESI ion source — "a vortex ESI ion source that improves sensitivity by increasing the efficiency of the desolvation process," Varian said in a statement.
According to Varian, "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."
Agilent Technologies this week launched the 1290 Infinity LC Injector HTS/HTC sample injection system.
According to the firm, the system offers fast speed, ultra-low carryover, and robustness for customers in need of high throughput. The injectors are the first high-throughput sample injection modules providing 1290 Infinity LC pressure capability at 1200 bar, the company said.
Agilent launched the 1290 system in April [See PM 04/30/09].
