摘要： An apparatus and a method for analysis of a particle by irradiation of the particle in a fluid with an intense laser pulse to cause laser breakdown and to detect sonic waves or plasma emission which are generated by the laser breakdown. The size of the particle is measured by using at least two kinds of information from the following: intensity of plasma emission or sonic wave generated by the laser breakdown, location of the laser breakdown plasma, and plasma emission waveform. Also, a laser pulse having flattened distribution of intensity for the irradiation is used in order to eliminate the dependence of the measured value on the particle location.

摘要： The power density of a pulsed laser beam for irradiating a sample is adjusted to break down the sample into the form of a plasma. After the momentary breakdown of the sample into the form of a plasma, ions are generated having a high charge. Then, after a certain time elapses, the ions having a high charge recombine with the electrons in the plasma to provide monovalent or low valent ions. These low valent ions are taken out of the plasma and introduced to a mass spectrometric apparatus.

摘要： This invention relates to an analytical method and a relevant equipment for particulate substances in a sample with the detection of acoustic waves generated in the sample with the irradiation of onto the sample. In this invention, the light power density of the irradiating light onto the sample is set high enough above the breakdown threshold of the particulate substances in the sample, and low enough below the breakdown threshold of the media, and the particulate substances in the sample are counted by detecting the acoustic waves generated by the breakdown of the particulate substances. The particulate substances are also analyzed for their components on the basis of the light signal (emission spectrum) which is detected with a dispersed spectrum from the light which is generated by the breakdown of the particulate substances.
