Bruker Introduces maXis™ HD Ultra-High Resolution QTOF at HUPO

At the 12th Human Proteome Organization World Congress, Bruker completed its series of High-Definition (HD) QTOF systems introductions with the launch of its new flagship maXis HD ultra-high resolution (UHR) QTOF mass spectrometer. With its best-in-class full sensitivity resolution (FSR) greater than 75,000, the new maXis HD is ideally suited for top-down proteomic analyses and the characterization of biopharmaceuticals.

The novel maXis HD features a new High-Definition Collision (HDC) cell which enables its record-breaking full sensitivity mass resolution, as well as accurate mass capabilities well beyond all competing QTOF systems. Due to its extreme sensitivity broad mass-transfer ion optics and the fastest available 50 Gbit/sec sampling technology, a dynamic range of 5 orders of magnitude is achieved in one second of LC time. High dynamic range at high speed is a prerequisite for high-resolution detection of low-abundance compounds in sharp UHPLC peaks and permits direct identification and quantitation without re-runs.

The maXis HD offers break-through analytical performance for applications in top-down proteomics and in biopharmaceutical compound analysis, and the instrument excels in the analysis of intact proteins and antibodies. For antibody subunits, it can provide unprecedented insight into antibody structures via its ultra-high resolution at high mass with baseline discrimination of isotope envelopes at excellent mass accuracy.

The maXis HD also delivers a new confidence level in the fast, high-resolution, accurate mass screening, identification and quantification of small molecules. The novel HDC cell and HD detection technology translate directly into enhanced dynamic range and extreme sensitivity down to very low masses at UHPLC speed, a precondition for one-shot plug & play acquisitions in multi-target applications. The recording-breaking full sensitivity resolution in combination with the Bruker proprietary, real-time SmartFormula™3D software makes the maXis HD the tool of choice for true unknown screening and the ab initio determination of elemental composition at UHPLC speed and throughput.

Dr. Michael Schubert, President of the Bruker Daltonics Life-Science & Clinical Division, stated: “With these performance features we believe that the new maXis HD delivers the fastest time-to-success for customers across a broad applications portfolio, covering small molecule identification and characterization; food, forensic and environmental screening; metabolomics; as well as top-down proteomics and antibody analysis. The new maXis HD is available for shipment immediately.”
