Abstract
A method and apparatus for the identification and detection of composition of a liquid are disclosed. The invention involves detecting and collecting spectroscopically resolvable information about incident radiation, and collecting one or more datasets of intensity information at the detector system. Each dataset is resolved across at least three frequency bands within the spectrum of the source to produce an intensity data item for each band. A numerical relationship is evaluated for at least two pairs of frequency bands in a given intensity dataset to obtain a numerical indicator functionally related to a characteristic physical material property such as a material coefficient that varies functionally with radiation energy. The numerical indicator is compared with a library of data for a range of potential component liquids in order to obtain an indication of the likely composition of the liquid sample. An apparatus for use in identifying and detecting a liquid is also disclosed.
