Property analysis methods and properties analyzer of liquid

摘要

PROBLEM TO BE SOLVED: To provide an analysis method and an analysis apparatus of a liquid for discriminating a type of the liquid.;SOLUTION: When an electrical signal with a different frequency is applied to the liquid, a phase difference is generated between a signal applied to the liquid and a signal extracted through the liquid and is different in accordance with the frequency. When a change of the frequency is considered as a horizontal axis and a change of the phase difference is considered as a vertical axis and described as a waveform diagram, the waveform diagram with a different pattern is described by each liquid. The type of the liquid can be discriminated by using the principle and describing a pattern diagram of the waveform. An aspect of the liquid can be assumed from the waveform.;COPYRIGHT: (C)2004,JPO
