A method is described for the quantitative multielement analysis of lubricating greases using inductively coupled plasma–atomic emission spectrometry. A key to this analysis is to prepare a sample solution by decomposing the grease sample through alternate means, such as ashing, microwave assisted ashing, or mineral acid decomposition. Results of an interlaboratory study conducted using this method are described.
