Abstract
Dual TDC-ADC detection systems for time of flight mass spectrometry are disclosed herein. Detection systems based upon TDC generally provide higher timing resolution as opposed to detection systems based upon ADC. However, ADC generally provides increased dynamic range over TDC. By combining TDC and ADC into a tandem detector, and adjusting performance parameters of the respective converter types, the dynamic range of the dual TDC-ADC detection can be extended beyond what either detector type could have achieved individually. Composite time of flight mass spectra can be generated by aggregating individual mass spectra acquired from multiple time-of-flight extractions, and selecting the number of time-of-flight extractions to ensure overlap between the ADC and TDC dynamic ranges in the dual TDC-ADC detector system.
