专利汇可以提供ULTRASONIC CHARACTERIZATION OF SINGLE DROPS OF LIQUIDS专利检索,专利查询,专利分析的服务。并且The present invention includes the use of two closely-spaced transducers (10, 16) or one transducer (40) and a characterization of droplet-size and smaller samples without the need for a container. The droplet (18) is held between the interferometer elements, whose distance apart may be adjusted, by surface tension. The surfaces of the interferometer elements may be readily cleansed by a stream of solvent followed by purified air when it is desired to change samples. A single drop of liquid is sufficient for high-quality measurement. Examples of samples which may be investigated using the apparatus and method of the present invention include biological specimens (teardrops; blood and other body fluid samples; samples from tumors, tissues, organs; secretions from tissues and organs; snake and bee venom, etc.) for diagnostic evaluation, samples in forensic investigations, and detection of drugs in small quantities.,下面是ULTRASONIC CHARACTERIZATION OF SINGLE DROPS OF LIQUIDS专利的具体信息内容。
