1. A chemical analysis device to analyze a chemical composition of a sample, comprising:
a main body that includes a laser light source, a chemical analysis unit, and a housing that houses the laser light source and the chemical analysis unit as having a pressure-resistant function; an optical head that is arranged to be faced to the sample; and a pressureproof-feedthrough-equipped fiber that is extended from the housing to the optical head to guide laser light emitted from the laser light source to the optical head, wherein the optical head includes a minor system that causes the sample to be irradiated with laser light outgoing from the pressureproof-feedthrough-equipped fiber and to cause plasma emission light occurring at the sample owing to irradiation with the laser light to reenter to the pressureproof-feedthrough-equipped fiber, the chemical analysis unit performs spectroscopic analysis on the plasma emission light that reentered to the pressureproof-feedthrough-equipped fiber, the optical head further includes a liquid discharging unit to clean a vicinity of the sample, and the liquid discharging unit includes a pump that draws liquid at the outside of the optical head, a filter that generates filtrated water by eliminating impurities from the liquid drawn by the pump, and a discharging portion that discharges the filtrated water generated by the filter to the vicinity of the sample. |
