DETERMINATION OF BIO-ACTIVITY

摘要

PURPOSE:To provide a process for the determination of bio-activity to enable the estimation of the activity of living cell and the determination of the concentration in a short time. CONSTITUTION:A specimen solution and a maleimide derivative are charged to a reaction tank 3 and mixed. The mixed specimen liquid containing a component emitting light with organism is retained for a prescribed period in the reaction tank 3 and transferred to a flow cell 5. Light having a definite wavelength is transmitted through a filter 9 and a condenser lens 10 and applied to the specimen in the flow cell 5. Light emitted from the specimen is passed through a condenser lens 11 and a filter 12, detected with a photomultiplier 13 and counted with a counter 14 to determine the number of living cells and the activity of each organism in the specimen solution.
