SWATH (Sequential Windowed Acquisition of all Theoretical fragment ions) is a powerful mass spectrometry method designed for detailed protein analysis. It works by dividing the mass range into sequential windows and capturing all fragment ions for each detectable precursor ion. As a result, SWATH allows for both accurate quantification and identification of peptides in complex samples, offering a complete and comprehensive proteomic profile.
