MS, time-of-flight

However, nowadays some other different mass spectrometers are used for ICP-MS time-of-flight (TOP) systems for multielemental analysis of transient signals, ion trap analysers for ion storage, multicollector instruments for precise isotope ratio measurements and double-focusing sector field mass spectrometers for high mass resolution, but still the majority of instruments are equipped with quadrupole filters, which are simpler and cheaper.

Meteor can be interfaced with the MetaboLynx mass spectrometer software from Waters Corporation to integrate mass spectrometry data from metabolism studies directly. MetaboLynx is part of the Waters MassLynx Application Managers, a suite of mass spectrometry instrument software [16]. It is designed for automated metabolism studies with data from LC/MS or LC/MS/MS time-of-flight (TOP) experiments. MetaboLynx is able to detect peaks in an LC/MS data file resulting from in vitro or in vivo biotransformation and provides a list of elemental formulae for unidentified components in a mass spectrum. Meteor uses these data to filter the list of predicted metabolites. System requirements are similar to DEREK for Windows.

Powerful new technologies of ion analyses (tandem MS, time-of-flight MS (TOF MS), and ion-trap MS) substantially increased the capability of MS analyzers with respect to specificity and the extent of data handling. The range of applications of LC-MS in the field of natural products is constantly increasing, especially with the introduction of tandem MS (MS/MS) for quantification and high resolution MS (HRMS) for unequivocal structural elucidation using mass accuracy and the elemental composition of precursors and product ions. 

TOF-MS (time of flight MS), with its high mass-resolving power is capable of generating mass data of sufficient accuracy and precision to establish the elemental composition of an analyte. The high accuracy, fast response time, and ease of peak deconvolution capability make TOF-MS an ideal online detector to interface with high-resolution separation techniques. The hyphenation of TOF-MS with CE...
