Bruker Announces Release of Breakthrough CaptiveSpray(TM) Nano/Capillary Electrospray Ion Source for Proteomics at ASMS 2011

At ASMS 2011, Bruker is introducing the breakthrough, proprietary CaptiveSpray electrospray ion source for nano-HPLC applications in proteomics. Using CaptiveSpray technology in many cases increases bottom-up protein identifications significantly, and CaptiveSpray is presently the best available technology for robust, reproducible protein ID or quantitative proteomics applications, with excellent, stable sensitivity over long time periods.
Unlike a traditional pulled nanospray tip, the Etch-Taper™ technology employed by CaptiveSpray ensures that the internal diameter of the spray tip remains constant, thereby reducing tip clogging, and providing excellent spray stability over the entire LC gradient and robust operation for long time periods, even with heavy proteomics samples loads. A key proprietary feature of the CaptiveSpray is its novel gas-flow focusing technology for dramatic sensitivity gains compared to normal electrospray. The CaptiveSpray source delivers nanospray sensitivity without the need for complex and time consuming spray tip adjustments, while its innovative plug-and-play design fits all current Bruker LC-MS instruments, including the latest maXis UHR-Qq-TOF systems, solariX FTMS systems and amaZon ETD ion trap mass spectrometers.
