  • Optical detector for flowing sample and optical detection method for flowing sample
    Patent number: 5661558
    Abstract: An optical detector for flowing sample comprises a light condenser for condensing a diverging monochrome light, a flow cell arranged in the course of convergence of the converged light beam, and a sample-side detector for receiving a sample-side light. Such a construction makes it possible to correct delicate changes of the light axis due to intensity, position, temperature changes of the light source, density change of the flowing liquid, and any change of other causes effectively for stable sample analysis without difficult optical adjustment.
