EU (European Union) is applying various regulations to poisonous chemicals in industrial products these days. ELV (End of Life Vehicles) Directives(July, 2003), RoHS (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment) Directives(July, 2006) including RoHS Directives for Japan and China, and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) Regulations have been applied to the control of poisonous substances in industrial products. Particularly, mercury is regarded as one of the control targets for specified toxic materials and must be controlled by the industrial manufacturers. Therefore, the measurement of mercury should be done by simple, safe and rapid procedures for multiple samples. The reduction-cold vapor atomic absorption spectrophotometric method which requires the wet pretreatment has been adopted as the official method in many countries. In the meantime, the thermal decomposition (gold amalgamation) method has been discussed as an alternative official analytical method for RoHS –related substances due to the freedom from interfering substances and dangerous reagents and its high sensitivity. In this presentation, the principle, operational easiness and actual measurement examples of the thermal decomposition (gold amalgamation) method and its instrumentation will be explained.
