Considerations in Applying Molecular Analysis of Different Fluids in a Condition Monitoring Program

Abstract

Molecular analysis of oils by Fourier Transform Infrared (FT-IR) spectroscopy is becoming commonplace in condition monitoring programs. Providing a fast, direct measurement on species and properties of interest, molecular spectroscopy can supplement or replace other measurement techniques which are time consuming, or provide only an indirect measurement of the properties of interest. Molecular spectroscopy also offers other capabilities, such as calibration to classical physical tests, or the identification of an unknown fluid by searching against a spectral library of known fluids. Here, we will review some of the promises and pitfalls in molecular analysis for a condition monitoring program, with emphases on the general capabilities of molecular spectroscopy, and the amount of useful information (to a condition monitoring program) which can be generated when progressively less information is known about the machine being monitored.
