Author Description

An account is given of an assessment of atomization and measurement procedures for the analysis of elements in dry samples of powdered ore. Two atomization procedures were studied: that using an air-acetylene flame, and that using electrical-resistance heating. The former procedure was found to be the more satisfactory, and resulted in reasonably good accuracy and precision in the determination of silver, bismuth, and cadmium at levels between 0,1 and 40 ug/g in a number of sample materials having widely differing matrices.
