Analysis of Lubricating Oils for Iron Content.

摘要

It is an object of this invention, therefore, to provide an improved method for determining the quantity of iron wear metal present in lubricating oils in both particulate and dissolved forms. Other objects of the invention are: to provide a method for conducting a rapid, on-the-spot quantitative test for a major wear metal contained in lubricating oils; to provide apparatus, which may be in the form of a kit, for carrying out the quantitative analysis of iron in lubricating oils; and to provide articles of manufacture which incorporate components used in the practice of the analytical method of this invention.
