Abstract:
A method of and miniaturized apparatus adapted for in-situ measurement of degradation of automotive fluids and the like by micro-electron spin resonance (ESR) spectrometry, wherein the use of a modulated constant magnetic field in an RF resonating variable frequency microwave cavity resonator through which a fluid sample is passed, enables direct detection of molecular changes in such fluid sample resulting from fluid degradation during use.
