PURPOSE:To recover a sample solution simply by providing a light projecting surface and a light receiving surface of two fibers sandwiching a cell and means for introducing and discharging the sample solution to measure the absorbance of an ultra-microscopic amount of the sample solution for a short time. CONSTITUTION:A sampling probe 10 is immersed into a solution to be measured and with a piston 12, the solution is introduced into a part 13c to be measured of a cell 13 through a sample solution path 10a. Light is made to irradiate the part 13c being measured through a light projecting fiber 6 and the light passing through the sample solution is introduced into a spectroscopy system through a light receiving fiber 7. After the measurement, with the movement of the piston 12, the sample solution is discharged and recovered. |
