[GDMS] Glow Discharge Mass Spectrometry
Dissociate and fragment specific mass ions, and detect them with a mass spectrometer.
GDMS is a method for analyzing the composition of solid samples, allowing simultaneous analysis from major components to trace elements, and performing semi-quantitative analysis of impurities present in the sample. The concentration conversion uses the relative sensitivity factor (RSF) associated with the device. The analytical values are derived from the ion intensities of the major component elements and the target elements, calculated using the RSF, resulting in semi-quantitative values. - Bulk analysis is possible from trace elements (ppb level) to major component levels. - Depth profile analysis on the order of micrometers and thin film analysis are possible. - By using conductive materials and auxiliary electrodes, analysis of semiconductor materials and insulating materials is also possible. - High mass resolution allows for the removal of interfering ions. - Measurement is possible for almost all elements below Li, excluding hydrogen and noble gases. - Isotope ratio measurement is possible.
