摘要： By use of excitation beam having a wavelength which is equal to, or close to, the sizes of particular particulate substances as the object of analysis, the particulate substances such as an immunoreaction product between an antigen and an antibody or between the antigen and a material supporting thereon the antibody are detected selectively. Very small particles having specific sizes such as rheumatuid factors, cancer specific antigens can be detected highly sensitively.

摘要： This invention relates to a method and apparatus for positron extinction analysis which radiates a positron beam to a sample to be analyzed through a convergent lens system consisting of a magnetic lens and measures the extinction γ-rays generated from the sample for the positron extinction analysis. The invention utilizes the property of the magnetic lens of an electron microscope that the magnetic lens has the same focal distance for both the positron and the electron that have mutually the same energy. If the magnetic lens of the electron microscope is used as a convergent lens system for a positron beam, the positron beam can be radiated highly accurately to a very small, local position of the sample which is being observed through the electron microscope. For instance, in the case of a transmission electron microscope, the convergent lens system of the position beam is used as the convergent lens system of the positron beam.

摘要： A medium (50) including particles (200) to be analyzed is contained in a cell through which excitation rays are passed. The excitation rays (100) are focused and have a predetermined wave form. A period in time of the excitation rays is set substantially equal to and preferably longer than the attenuation time of an acoustic pulse which is generated when the excitation rays are absorbed in the particle and when the particle release heat. The acoustic pulse is used to analyze particle size and number of particles.
