High-Performance LC Triple Quadrupole Mass Spectrometers
Jul 19 2013
At the 2013 American Society of Mass Spectrometry Meeting (ASMS), Bruker showcased three game-changing LC-triple quadrupole (LC-TQ) mass spectrometers, the high-performance EVOQ QubeTM, the ultra-high sensitivity EVOQ Elite, and the extended mass range EVOQ Elite ER, which are setting new standards for analytical performance and quantitative robustness.
All EVOQ LC-TQ systems premiering today incorporate Bruker’s new Advance™ Ultra-High Pressure Liquid Chromatography (UHPLC) systems. The Advance HPLC, UHPLC, and the UHPLC-OLE products offer ultra-low dead-volume which enables excellent reproducibility at analytical flow-rates, an integrated column-oven, and bench-space savings. Paired with the industry workhorse CTC auto-sampler, the Advance LC portfolio delivers precision and accuracy required for sustained, high-sensitivity LC-MRM quantitative analysis.
In addition, the EVOQ platform features several major innovations: the industry’s first Vacuum-Insulated Probe (VIP) heated electrospray technology preserves and ionises thermally fragile molecules with outstanding sensitivity; the Active Exhaust atmospheric pressure ionisation source with a robust orifice vacuum interface significantly enhances quantitative robustness for difficult samples; the novel, ‘flat-tuning’, proprietary Interlaced Quadrupole Dual Funnel (IQ-DF™) maximises sensitivity; novel PACERTM software enables ‘exception based data-review’, a revolutionary feature that significantly reduces the error rate for quantitative analysis
Bruker’s patented lens-free triple-quad mass filter design, which enhances MRM performance, comes standard on all EVOQ systems, making the EVOQ LC-TQ inherently easier to use and maintain. Other high-performance TQ features include Bruker’s unique Compound Based Scanning (CBS) technology, the novel VIP heated-ESI and APCI ion sources, fast 14,000 amu/sec scan speed and 25 msec positive/negative ion switching, all for leading-edge TQ performance and analytical power.
Kefei Wang, EVOQ Senior Product Manager, said: “The EVOQ Qube and Elite have delivered to the expectations of our customers. In the short time since the launch we have been receiving repeat orders. This is the true measure of success. Now we add the EVOQ Elite ER which provides extended mass range to 2000 m/z, providing more capability and range for our current and future customers.”
