In the x-ray fluorescence analysis of minerals, ores and other materials, chemicals containing lithium and boron are melted together at high temperatures to produce a borate of lithium which is then cooled and reduced in size to a powder or coarse material. Such material Is known as x-ray flux and is usually represented or specified in the final commercial product as ratios of lithium tetraborate to lithium metaborate. The x-ray flux is melted with materials to be analyzed and cast into discs which are then analyzed by an x-ray fluorescence spectrograph. In this invention, tantalum or tantalum compounds have been added, mixed and melted with the x-ray flux such as to function as an internal standard for the quantitative analysis of copper in copper containing substances, copper ores or copper concentrates, when such flux is mixed and melted with the copper containing samples to be analyzed.
