Abstract
Provided are a total organic carbon measurement method and a total organic carbon measurement device capable of determining whether or not an acid has been added to a sample. An acid is introduced into a reaction unit in which the sample is placed from a reservoir in which the acid is reserved (step S). The conductivity of the sample into which the acid has been introduced is measured (step S). The introduction of the acid from the reservoir into the reaction unit is detected on the basis of a change in the conductivity of the sample (step S).
