Abstract
Multiplexed ion mobility spectrometry (IMS), mass spectrometry (MS) such as time-of-flight mass spectrometry (TOFMS), or hybrid IM-MS is carried out on a sample, and the resulting measurement data are deconvoluted. A pulse sequence controlling ion pulsing is utilized in conjunction with the multiplexing. The pulse sequence may be modified based on the raw measurement data acquired. A demultiplexing matrix based on the modified pulse sequence is utilized to improve deconvolution.
