Accurate and on time diagnosis of engine and machine wear can effectively reduce the maintenance and potential breakdown costs. Monitoring the additive elements, wear metals, and contaminants in lubricating oils is an effective method to assess the condition of lubricating oil and engine. Inductively coupled plasma optical emission spectrometry (ICP-OES) can be used for the determination of metals content of used and unused lubricating oil. To accomplish testing for metals in lubricating oils, laboratories typically adhere to standard test methods from organizations such as ASTM. In this work, we demonstrated the performance of Shimadzu ICP-9820 for ASTM D5185 method and analyzed used and unused lubricating oil samples to determine the accuracy, precision, and robustness of the system. The results demonstrated that the method performed well to ensure meeting all the criteria established in ASTM D5185. The vertical orientation of the torch in Shimadzu ICP-9820 is ideally suited for analysis of lubricating oil. This torch orientation minimizes the carbon build-up (soot), allowing for samples diluted in organic solvent to be analyzed without the introduction of oxygen. Its vacuum-purged optical bench precludes the need for purging gas, reduces the start-up time, and improve sensitivity in the deep ultraviolet range. The features of the ICP-9820 provides excellent precision, accuracy, tolerance, and fast response to meet and exceed compliance with regulations on elemental analysis of lubricating oils.
