Measuring TAN/TBN with Infrared Spectroscopy
This white paper explores IR spectroscopy as an alternative method for measuring TAN and TBN values, using a 3-step process of library building, sample classification, and multivariate regression techniques. The authors present the principles of IR spectroscopy as it relates to TAN and TBN measurements, the advantages and disadvantages of the method, and specific examples of its application for various types of engines and lubricants.
