3 terms and units of measure

3.1 Quality range The mass range represents the mass interval of the element (isotope) that the mass spectrometer can measure, in atomic mass. Unit u. 3.2 resolution The resolution is expressed as the peak width at 10% of the peak height of an element, in units of u. 3.3 Detection limit The minimum limit mass concentration of an element that can be measured by a mass spectrometer. The representation method is n of an element in a blank solution The mass concentration corresponding to the standard deviation of 3 times of the sub-measurement result. Unit ng·L-1. 3.4 Sensitivity The signal response (count) obtained by the element concentration unit on the mass spectrometer detector, in units of Mcps/ (mg·L-1). 3.5 Abundance sensitivity Abundance sensitivity characterizes a strong ion peak of mass M at the adjacent mass M 1 (or M-1) The effect of a front or trailing peak on an adjacent peak. Dimensionless. The abundance sensitivity is expressed by the following formula. δ=IM 1IM Or δ=IM-1IM (1) Where. δ---abundance sensitivity, dimensionless; IM---mass is the signal intensity of M strong ion peak, cps; IM-1---the tailing signal intensity of the ion peak of mass M at the mass M-1 position, cps; IM 1---Tail signal strength at the mass M 1 position of the ion peak of mass M, cps. ......
