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 S103). The conductivity of the sample into which the acid has been introduced is measured (step S105). 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 S107).

A total organic carbon measurement method comprising:
- introducing an acid from a reservoir in which the acid is reserved into a reaction unit in which a sample is placed;
- measuring conductivity of the sample into which the acid is introduced;
- and
- detecting the introduction of the acid from the reservoir into the reaction unit on a basis of a change in the conductivity of the sample.
A total organic carbon measurement device, comprising:
- a reaction unit in which a sample is placed;
- an addition unit configured to introduce an acid into the reaction unit from a reservoir in which the acid is reserved;
- a first conductivity measurement unit that measures conductivity of the sample into which the acid is introduced;
- and
- a determination unit that determines the introduction of the acid from the reservoir into the reaction unit on a basis of a change in the conductivity of the sample.
