Asimple, enclosed device for sample dissolution under normal pressure is suggested in this paper. It eliminates the dissolved components of aqua regia produced in the process so as to protect the health of the analysts and to avoid environment pollution. This method has been used in the pilot determination of trace gold in various types of ores and other materials, and the results are compared and proven to be satisfactory.
