Abstract: Systems and methods are described for analyzing local minimum data from spectrometry data for the determination of nanoparticle detection thresholds are described. In aspects, a histogram of the spectrometry data is used to search for potential local minimum values, which are subsequently validated to establish a nanoparticle detection threshold for the spectrometry data, with ion intensity values less than the nanoparticle detection threshold being attributable to signal background.
