| Abstract: | The instrument parameters were optimized,then 27 kinds of trace impurities in high purity rubidium chloride were determined by inductively coupled plasma mass spectrometry(ICP-MS).The mixed internal standard of Be,Sc,Y,Rh,In,Re was used to correct the signal shift of instrument and matrix effect.The concentration of each element was linear with the intensity of signal,and the linear correlation coefficients were 0.986 3-1.000 0.The detection limits were 0.003-0.66 ng/mL.The relative standard deviation decre... |
