1.1 This guide describes procedures for use in conducting analysis of silver-cadmium oxide materials for sodium and potassium content. The exact methods for the performance of this testing are not stated since many different procedures are equally applicable. This guide points out specific procedures for decreasing the chance of recognized potential errors and specifies methods for increasing the sensitivity of the testing.

1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use. For specific precautions see Sections 4 and 6.

1.3 Whoever uses this standard should consult the Material Safety Data Sheet concerning the products involved.


This guide is recommended for use in analyzing the sodium and potassium content of silver-cadmium oxide materials and is meant to be used in conjunction with standard methods of atomic absorption spectroscopy. The recommended procedures cite methods for minimizing extraneous sodium and potassium contamination through use of specific handling procedures and shorter sample preparation methods. This guide also recommends procedures that prevent the formation of nonstable and potentially hazardous silver-acetylene compounds.
