ABSTRACT:
An optical particle analyzing apparatus includes a flow cytometer in which laser light and lamp light having a wavelength shorter than that of the laser light are used simultaneously when particles in a blood specimen or the like are analyzed by the flow cytometer. Scattered light emitted by a particle due to irradiation with the laser light and fluorescence emitted by the particle due to irradiation with the lamp light are detected. A signal indicative of the scattered light is used as a timing signal to detect the fluorescence. This arrangement makes it possible to reduce the size and cost of the apparatus.
