Abstract: A signal processing method (100) of a mass spectrometer signal, indicative of mass spectrum of atoms abundant in the mass spectrometer analyzed sample, where the signal processing method comprises: segmentation of the spectra (102), compression of the data points (103), peak finding from the spectra (104), ridge detection (105) at the adjacent peaks represented but the consecutive spectra, peak data processing (106), and identification of peaks (107). The signal processing method is used in a mass spectrometer and a mass spectrometer system.

Abstract: Disclosed are embodiments directed to a multi-ion identification device, a system and method using the same to utilize chemical ionization in multiple adduct formation from the substances in the sampled gas of a gas sample being addressed to be analyzed in a mass analyzer. The multi-ion identification device includes a buffering region to have the sample flow turbulence decayed before the sample flow entrance to the ionization region)) utilizing chemical ionization by reagents from an ensemble of reagent ion towers.
