Shimadzu LCMS-9050 Quadrupole Time-of-Flight Liquid Chromatograph Mass Spectrometer
Brochures and specifications | 2025 | ShimadzuInstrumentation
The development of high-resolution quadrupole time-of-flight (QTOF) liquid chromatography-mass spectrometry (LC-MS) instruments addresses critical needs in pharmaceutical analysis, metabolomics, environmental screening and complex sample profiling. Reliable accurate-mass measurements and efficient workflows accelerate compound identification, impurity profiling and high-throughput screening in research and quality control laboratories.
This application note presents the LCMS-9050, a QTOF mass spectrometer engineered for ultra-stable mass accuracy, rapid polarity switching and adaptable front-end configurations. It aims to demonstrate performance advantages in continuous analysis, positive/negative ion switching, throughput improvement and seamless integration with optional ionization sources and sample prep modules.
The LCMS-9050 combines patented Shimadzu technologies for enhanced ion focusing, temperature-controlled flight-tube stability and a proprietary UFstabilization™ algorithm. Key features include:
Continuous analysis of six antibiotics (m/z 265–1203) over 72 h yielded mass errors within ±2 ppm in single-mode and within ±3 ppm with external calibration in positive/negative switching mode. Temperature variations were effectively mitigated. The ability to switch polarity in a single run doubled throughput versus separate analyses and ensured simultaneous detection of analytes under identical conditions. Case studies:
The LCMS-9050 represents a new generation of QTOF mass spectrometers, delivering exceptional mass accuracy, ultra-fast polarity switching and flexible modularity. These capabilities enable robust high-throughput workflows, precise compound identification and versatile application across diverse analytical challenges.

Summary
Significance of the Topic
The development of high-resolution quadrupole time-of-flight (QTOF) liquid chromatography-mass spectrometry (LC-MS) instruments addresses critical needs in pharmaceutical analysis, metabolomics, environmental screening and complex sample profiling. Reliable accurate-mass measurements and efficient workflows accelerate compound identification, impurity profiling and high-throughput screening in research and quality control laboratories.
Objectives and Overview
This application note presents the LCMS-9050, a QTOF mass spectrometer engineered for ultra-stable mass accuracy, rapid polarity switching and adaptable front-end configurations. It aims to demonstrate performance advantages in continuous analysis, positive/negative ion switching, throughput improvement and seamless integration with optional ionization sources and sample prep modules.
Methodology and Instrumentation
The LCMS-9050 combines patented Shimadzu technologies for enhanced ion focusing, temperature-controlled flight-tube stability and a proprietary UFstabilization™ algorithm. Key features include:
- Precision temperature control and auto-tuning for extended mass accuracy without frequent calibration
- Fast polarity switching with low-ppm accuracy in under 100 ms transitions
- Modular front-end extensions such as DPiMS™ direct probe ionization, iMScope™ imaging microscope, CLAM™ automated sample prep, OAD radical source for lipid bond localization, SFC coupling (Nexera™ UC) and micro-flow LC-MS (Nexera Mikros™)
Main Results and Discussion
Continuous analysis of six antibiotics (m/z 265–1203) over 72 h yielded mass errors within ±2 ppm in single-mode and within ±3 ppm with external calibration in positive/negative switching mode. Temperature variations were effectively mitigated. The ability to switch polarity in a single run doubled throughput versus separate analyses and ensured simultaneous detection of analytes under identical conditions. Case studies:
- Atorvastatin calcium impurity profiling: simultaneous positive/negative scan detected parent drug and EP-specified impurities within ±1 ppm mass accuracy
- Supercritical fluid chromatography coupling: 80 pesticides screened in one run with high sensitivity and resolution
Benefits and Practical Applications
- Streamlined workflows by combining positive and negative ion analyses in a single injection
- Reduced calibration downtime via auto-tuning and stable temperature control
- Enhanced confidence in compound identification through high-accuracy mass measurements
- Scalable solutions for rapid screening, imaging, direct sample analysis and automated prep
Future Trends and Potential Applications
- Further integration with artificial-intelligence-driven data mining and library matching
- Expansion of advanced fragmentation techniques (OAD, CID-HR) for structural elucidation of lipids and metabolites
- High-throughput screening in metabolomics, proteomics and environmental monitoring using modular front-end modules
- Broader adoption of micro- and nano-flow LC-MS for trace-level quantitation in biologics and pharmaceutical R&D
Conclusion
The LCMS-9050 represents a new generation of QTOF mass spectrometers, delivering exceptional mass accuracy, ultra-fast polarity switching and flexible modularity. These capabilities enable robust high-throughput workflows, precise compound identification and versatile application across diverse analytical challenges.
