This method is for determining the total chloride content of liquid hydrocarbons by wavelength dispersive X-ray Flourescence (XRF) spectroscopy. The example given here focuses specifically on gasoline matrix but other hydrocarbon matrices are applicable if calibration standards of similar matrix are used. Highly volatile hydrocarbon species (e.g. LPG) are not applicable. The calibration has been set up for quantitative determination chloride from 5 mass-ppm to 1000 mass-pmm (0.0005 mass-% to 0.1000 mass-%). Matrix effects are not significant over this range so long as routine samples and calibration standards are well matched.
