DISPENSING METHOD

摘要

PURPOSE:To execute dispensing with high accuracy and to improve measuring accuracy in an emission analysis method by containing preliminarily a reagent into a dispenser having a dispensing needle and operating the dispenser by a movable device thereby injecting the reagent into a measuring cell. CONSTITUTION:The reagent such as oxidizing agent or catalyst is preliminarily contained into the dispenser 2 having the dispensing needle 3. A specimen contg. a chemical luminous material or bioluminous material (e.g.; luminol) is put into the measuring cell and the reagent is injected into the cell 5 by operating the dispenser 2 with the movable device 1 provided to the dispenser 2. An emission analysis is made by utilizing the light emission. It is also possible to provide 2 pieces of the dispensers 2 containing preliminarily the reagents into the respective dispensers and to operate the dispensers by the device 1 to inject simultaneously the reagents into the same cell 5. An air cylinder utilizing air pressure or a method for driving electrically a motor is applied to the device 1.
