Abstract
A system and method for quantitatively characterizing moisture content of an at least partially hydrophobic fluid sample. The method includes providing a dry solution of an aprotic solvent, adding at least a part of the fluid sample to the solvent to produce an extract-sample, performing infrared spectroscopic testing on the extract-sample to generate absorbance data representing at least one absorbance characteristic of the extracted sample, and generating moisture data for the sample based on the extracted sample data. The system includes a cell for holding and evaluating an extracted sample, an infrared spectrometer for measuring infrared absorbance characteristics of the extracted samples, a computer equipped with software for analyzing data outputted by the infrared spectrometer and utilizing an empirical model to derive at least one calibration equation relating data representing the absorbance characteristics of the extract-sample to unit moisture concentration, and converting the unit moisture concentration to a measure of moisture content of the sample. The method also utilizes DO to characterize moisture content of the extraction solvent, and compensate for both moisture content of the extraction solvent and matrix effects stemming from miscibility of the hydrophobic fluid in the extraction solvent.
