Study on the determination of major, minor, and trace constituents in meteorites by inductively coupled plasma-atomic emission spectroscopy (ICP-AES)
A study on the ICP-AES determination of 42 major and trace elements in meteorites was described. The sample was dissolved in a mixture of aqua regia and HF in a sealed Teflon bomb and boric acid is added after dissolution to complex the excess HF. The final solution is transformed into an aerosol via ultrasonic nebulization. The reference solutions employed for calibrating the spectrometers contained only the HF-aqua regia-HS/sub 3/BO/sub 3/ matrix. A polychromator and a programmable scanning monochromator interfaced to the same plasma excitation source provided the spectroscopic data. The accuracy of the determination was assessed by: (a) comparing our results with those obtained by neutron activation and x-ray fluorescence; and (b) by analyzing several geological reference samples (US Geological Survey and Canadian Certified Reference Materials). The analytical results showed good agreement. The relative standard deviation of the determination of the major elements ranged from 0.5 to 2%, and of the minor and trace elements from 0.5 to 8%.
