Title: Optical measurement of liquid sample
Inventor: MATSUMOTO SHINICHIROU
IPC: G01N21/01
Filed: 1979-06-13
Abstract: PURPOSE: To accomplish highly accurate measurement with a small amount of sample by incorporating the agitator into optical measuring cell.  
     CONSTITUTION: A prism-shaped agitator 2 transparent and sufficiently large with respect to the cell capacity is arranged in the anglar optical measuring cell. Sample 3 is placed in the cell 1 and the light transmission level of the sample 3 is measured while it is being turned in the optical path of the measuring beam. This can reduce the capacity of the space in the cell 1 so much to cover small amount of sample. At the same time, the existence of the agitator in no way blocks the measurement and thus, measurement can be done in the part subject to direct agitation by the agitator. Shorter effective optical path length can increase the absorbancy and the degree of scattering of the sample 3 per unit optical path length.
