Ion Transmission in the first vacuum stage of an Inductively Coupled Plasma Mass Spectrometer
… the problem may be due, at least in part, to the vacuum interface used to couple the plasma source and mass spectrometer. The research herein is a study of matrix effect sources in the first stage of the vacuum interface. This study utilized laser-induced fluorescence of atomic species to identify …

Velocity and Temperature Characterization of the First Vacuum Stage Expansion in an Inductively Coupled Plasma - Mass Spectrometer
… a behavioral baseline for neutral species in the first vacuum stage expansion of an ICP-MS. Velocities were determined from the Doppler shift of laser-induced Ar (I) fluorescence compared to stationary population wavelength reference. Unambiguous evidence of a thick Mach disk forming 10-12 mm …
