In this work, beach sand samples were washed with distilled water, dried, powdered (using hand mortar) then pressed into a pellet for analysis. A range of some 20 elements were identified, but the Ti concentration only was quantified. Quantification in an unknown sample involved the construction of calibration curves using standard additions for 6 different Ti peaks . A non-gated, non-intensified CCD was used for this analysis.
