Data Independent Acquisition (DIA) is a new, holographic independent data acquisition and quantitative technique based on the trajectory of the electrostatic field. The scanning range is divided into a series of intervals with an interval of 25 Dalt, and all the peptide parent ions in the scanning interval can be scanned at ultra-high speed and secondary fragmentation, obtaining the complete peptide information. Compared with the traditional proteomics using Data Dependent Acquisition (DDA) strategy, DIA technology avoids the bias of DDA strategy for high-abundance peptide collection and fragmentation, and DIA technology has a significant advantage for the quantification of low-abundance peptides. SWATH provided by CD Mitochondria is a special variant of DIA.
