Abstract
A method of determining the amount of water in an industrial oil (e.g., turbine oil) includes homogenizing an oil sample, subjecting the homogenized sample to infrared spectroscopy within 30 minutes of homogenization, and determining a baseline absorbance level for the sample within a predetermined wavenumber range. That baseline is compared with spectral template baselines and, based on the comparison, the amount of water in the oil sample is estimated.
