how to manipulate the time-of-flight mass spectrometry detection system and system

摘要

In this specification, I will disclose the time-of-flight mass spectrometer for dual TDC-ADC detection system. The TDC detection systems based, in general, as compared with the detection system based ADC, timing resolution is high. Meanwhile, ADC, generally, compared to TDC, a wide dynamic range. By constructing a tandem detector by combining the ADC and TDC, to adjust performance parameters of the transducer of each type, the detector of each type can be achieved by itself, the dynamic range of the dual-TDC-ADC detection It is possible to expand the dynamic range from. By aggregating the individual mass spectra obtained from time-of-flight plurality of extracted, and selecting the number of the flight time extracting dynamic range between the TDC and the ADC so as to overlap partially with certainty in a dual TDC-ADC detection system , it is possible to produce a mass spectrum composite flight time.
