Book Description
New high-grade cathode specifications are including specific impurity limits to meet the more stringent requirements of the continuous cast rod market. Improved cathode sampling and analytical methods are necessary to confirm specification compliance. A better sampling plan is to collect either saw cuttings or cut sections from the cathodes which would then be melted and cast to obtain adequate impurity representation. Interest in obtaining lower impurity detection limits is leading to more support for the electrothermal and vapor generation methods of atomic absorption spectrometry. Even after the improved methods of sampling and analyzing copper cathodes have been tested and adopted, frequent interaction between the cathode producer and consumer will be important to monitor product quality compliance.

Book Description
Draft for Development 78 (DD78), "Higher Purity Copper Cathode", published by the British Standards Institution requires the support of agreed methods of sampling and analysis capable of showing whether the impurities specified are below the limits set. This paper summarizes the state of development of methods for sampling and analysis of high-purity copper cathode arrived at in the U.K. with international support. The aims of work in progress are discussed.

Book Description
In order to devise a system for the sampling of copper cathodes using a mechanical punch it was first necessary to establish the distribution of impurities between individual samples and their location. To do this a cathode was divided into 171 pieces and each piece melted individually. Samples for analysis were then taken from the melt by suction through a 3.8-mm-ID glass tube and analyzed for impurities by emission spectrometry. The results obtained were summarized and studied statistically to determine the average content and standard deviation.
