Abstract
In the present invention, microplastics in a sample W are stained with a fluorescent material, the sample is irradiated with fluorescence-purpose excitation light and fluorescence emitted from the fluorescent material is detected, the position of the microplastics in the sample is identified by the fluorescence, the identified position is irradiated with Raman-purpose excitation light and Raman scattered light is detected, and the microplastics at the position are analyzed on the basis of the Raman scattered light.
