Mass spec cycle time
WebA method to control the duty cycle of a time-of-flight mass spectrometer is described. The method relies on one or more ion gates placed in the beam path that have the function to transmit or stop the beam. These ion gates can switch from the open state to the closed state in tens of nanoseconds and effectively select portions of the mass range. WebScientists withdrew thousands of pounds in pounds 5, pounds 10, pounds 20 and pounds 50 notes from various banks around Birmingham and tested them for traces of hard drugs - …

WebThe two mass spectra look like this: As you've seen, the mass spectrum of even very similar organic compounds will be quite different because of the different fragmentation patterns that can occur. Provided you have a computer data base of mass spectra, any unknown spectrum can be computer analyzed and simply matched against the data base. http://mass-spec.lsu.edu/msterms/index.php/Scan_cycle_time

WebMultistage MS (MS n) is a technique of performing multiple mass analysis in a single instrument and usually requires a time-based MS. Using ion trap MS as an example, the introduction of ions, selection of precursor ions, fragmentation and analysis of product ions are all performed in a single mass analyzer.

As to 12 data points per peak, we need to set up the dwell time for each ion (transition) as follows: - the number of cycles per second: 12 : 2.5 = 4.8 cycles/second. - cycle time for 8 components : 1 : 4.8 = 0.208 s = 208 ms. - dwell time for each transition: 208 : 8 = 26 ms.
