The Bruker Impact II is a high-resolution QTOF (Quadrupole Time-of-Flight) mass spectrometer, renowned for its ultra-high resolution and accurate mass capabilities in LC-MS and LC-MS/MS applications. It is designed for comprehensive qualitative and quantitative analysis, particularly in proteomics and metabolomics, offering deep insights into complex samples. Key technical specifications include a full sensitivity resolution (FSR) of greater than 60,000 and superior 1 ppm mass accuracy, ensured by automated calibration. It features a 50 GBit/sec sampling technology, maintaining full specification resolution even during ultrafast chromatography. The Impact II incorporates a dual ion funnel, ESI and HESI sources, and a collision cell with broad mass transfer, enabling high sensitivity and a five orders of magnitude dynamic range. Applications span ultra-high resolution, accurate mass (UHRMS) analysis, targeted and untargeted metabolomics, intact protein analysis, and shotgun proteomics. It is ideal for identifying unknown compounds, drug metabolite identification, and biomarker discovery and validation. The system's robustness and sensitivity make it suitable for definitive trace analysis from complex, high-background matrices. The Impact II is designed for ease of use and integration, allowing seamless hyphenation with UHPLC, GC, CE, or IC systems, with modality switching taking less than 10 minutes. It supports intelligent self-optimizing MS/MS routines and offers low picogram sensitivity for highly precise MS and MS/MS data.
