摘要： An apparatus for analyzing a used lubricating oil for iron wear metal content which comprises a series of containers, at least one of which is adapted for holding a test sample material while the remaining containers are adapted for holding 3 separate reagent sample materials. Also included are a reaction chamber, means for transferring the test sample material and the reagent materials from the series of containers to the reaction chamber which may also function as a test cell.

摘要： A method for analyzing a used lubricating oil for iron wear metal content in which all of the iron in a sample of the oil is extracted into an oil immiscible layer, buffering and reducing agents are added, and the iron in the solution is reacted with a chelating agent to forma red complex indicative of the iron content. Apparatus for carrying out the method comprises six containers, one for a lubricating oil sample and each of the other five being for a separate reagent. Also included are a reaction chamber, means for transferring oil sample and reagents from the containers to the reaction chamber which may also function as a test cell.
