PROBLEM TO BE SOLVED: To remove contaminants from a probe effectively. SOLUTION: At the position of a cleaning bath 20 for inserting a sampling probe 16, a cleaning water introduction pipe 23 is provided while surrounding the sampling probe 16 and a vacuum pump 27 is provided while being coupled with a vacuum pump for sucking outer air through the cleaning water introduction pipe 23. Cleaning water is delivered to the sampling probe 16 while sucking outer air through the vacuum pump. Since turbulence is generated in the cleaning water introduction pipe 23, samples adhering to the sampling probe 16 can be washed away cleanly and effectively by means of water flow and air flow. |
