A REAGENT INJECTOR BASED ON THE DROP-COUNTING METHOD AND AN ALKALINITY AUTO-ANALYZER

摘要

The present invention relates to a reagent injection device, and more particularly to a reagent injection device for injecting the correct amount of reagent by counting the number of drops of the solution reagent introduced in the water sample analysis.;The reagent injection device according to the present invention is scattered by the reagent chamber containing the reagent, the reagent chamber portion of the reagent chamber portion formed by the reagent droplet and the tip portion for injecting the formed reagent droplet into the sample and the reagent droplet injected from the tip portion It characterized in that it comprises a reagent droplet detection unit for detecting the reagent droplet using light.;Another technical problem to be achieved by the present invention is to automatically measure the alkalinity of the sample by counting the number of drops of reagent injected during the neutralization titration of the sample, and calculating the amount of reagent injected based on the counted number of reagent drops. To provide a device.;Reagent injection device, drop counting method, automatic alkalinity measuring device
