Description:
The LTQ XL linear ion trap provides very fast speed while ensuring excellent sensitivity. The LTQ XL ion trap mass spectrometer extends the traditional MSn performance of LTQ ion traps by integrating more technologies to generate structural information through Thermo Scientific's innovative ion trap technology.

characteristic:

• Unparalleled sensitivity and unparalleled MSn mass spectrometry quality
• Pulse Q-dissociation (PQD) can generate more fragments, expanding the range of low-quality numbers
• High resolution separation (HRI) achieves the separation of mass peaks of the same heavy elements, which can obtain clearer MSn mass spectra
• Ultra fast polarity switching for high-sensitivity analysis of unknown substances
• Neutral loss of automatic data dependency for PTM and biotransformation analysis
• Using Ultra ZoomScan ™ Accurate determination of charge state
• Upgradeable to Thermo Scientific ™ LTQ Orbitrap XL's high-resolution and precise quality technology

The LTQ XL has simultaneously expanded the functionality and operational performance of ion trap mass spectrometry, with new features including:
The upgradable electron transfer lysis (ETD) module can provide protein post-translational modification information that traditional lysis methods cannot obtain
The pulse collision energy induced dissociation (PQD) function can provide information on low-quality fragment ions
High selection MS/MS analysis provides better matching of spectra in databases and spectral libraries, improving the reliability of structural confirmation. In addition, rapid polarity switching and mother ion related MS3 data correlation scanning can enable intelligent and rapid analysis of post-translational modifications and metabolite composition identification. It can also be combined with high-end cyclotron resonance mass spectrometry to form a multi-stage high-resolution hybrid mass spectrometer.
LTQ XL uses the Xcalibur operating platform, in conjunction with application software such as Mass Frontier, MetWorks, and BioWorks, making it a highly suitable choice for proteomics research, metabolite structure identification, quantitative drug screening processes, forensic and clinical testing.
