【Abstract】 An instrumental method for measuring the properties of liquids has been developed. The instrument, called the fiber capacitive drop analyzer (FCDA),is based on a specially designed drop sensor by means of the fiber drop analyzing technology and the capacitive drop analyzing technology,and produces a volume based fiber drop trace (VFDT),which shows the relation between the light intensity passing through the liquid drop and the instant drop volume. Preliminary experiments have been carried out and these prove that VFDT externalizes the overall properties of tested liquids and is suitable for fine discrimination among different kinds of liquids. VFDT is also potentially capable of simultaneously measuring the physical and chemical properties of liquids.更多还原
