Notes:
A ‘single pass’ method of analysing silicate rocks for their major element composition has been developed using a Philips 1212 x-ray fluorescence spectrometer. Samples need only be submitted once to the spectrometer and all ten major elements (SiO2, TiO2, Al2O3, Fe2O3T, MnO, MgO, CaO, Na2O, K2O and P2O5) are determined using a Cr x-ray tube and three analysing crystals, i.e. TIAP, PET and LiF220. The method has been evaluated in terms of the quality of the calibration lines for each element, the precision of replicated analyses and by the analysis of rock standards as unknown samples. The single pass method is rapid, facilitates on-line data reduction and is capable of producing high quality analytical data.
