小中大Ballistic Ion Extraction (patent pending) , 岛津 LCMS-IT-TOF 液质联用仪的专利技术,具体怎么样的,偶也不清楚! 你可以参考附件里的介绍! 呵呵,希望有助于你理解!
Features
Featuring MSn Capability
Shimadzu's new LCMS-IT-TOF is a novel hybrid mass spectrometer for biomarker discovery, metabolite identification and human health research, and ideal for applications in forensics, drug development, and environmental chemistry. Coupling atmospheric pressure ionization with Ion-Trap (IT) and Time-of-Flight (TOF) technologies, the LCMS-IT-TOF delivers high mass accuracy and high mass resolution (10,000 at 1000 m/z) independent of MS mode.
The LCMS-IT-TOF allows more qualitative information about a sample to be collected in a single run.
This enables researchers and scientists to:
Elucidate structures of new molecules
Identify impurities and contaminants
Analyze metabolites and biomarkers to evaluate biological pathways
The LCMS-IT-TOF has been designed to maximize sensitivity and selectivity by optimizing the ion transport to the TOF analyzer and redefining the capability of the quadrupole ion trap. The ion trap is used to focus ions before ejection into the TOF as well as supporting MSn analysis with effective precursor ion selection capabilities (resolution > 1,000 at 1,000 m/z).
The new instrument incorporates a host of new technologies and enhancements, including:
Compressed Ion Injection (patented)
Ballistic Ion Extraction (patent pending)
Dual-Stage Reflectron (patent pending)
New ion transfer optics
Temperature control of the flight tube
The source design, desolvation capillary and reduced collision ion focusing Q-Array were adapted from Shimadzu's successful single-quad HPLC mass spectrometer.
Combining new, innovative technologies with one of the fastest polarity switching speeds available, the LCMS-IT-TOF expands the power of mass spectrometry scanning to deliver unparalleled performance for the most demanding analytical needs.
