One technique frequently used for the quantitative analysis of material containing inorganic compounds is energy dispersive X-ray fluorescence spectrometry. It has been shown previously that this technique can be readily used to determine the retentions of chromated copper arsenate and ammoniacal copper arsenate treated wood. This paper reports the results of a preliminary study to determine whether energy dispersive spectrometry may be used to assay both organotin treated wood and also the preservative in solution. Five objectives were established for the study and they were (i) Assessment of the instrumental error; (ii) Determination of the error due to sample preparation; (iii) Selection of a suitable live data accumulation time; (iv) Preparation of a calibration graph using tributyltin acetate; and (v) To initate studies on interelement interference effects.
