Monitoring analysis device and monitoring analysis method

A monitoring analysis device comprising:

• an acquirer, an analyzer, a pre-processor, and a controller,
• wherein the controller is programmed to:
• control the acquirer to sequentially acquire reaction products produced by a reactor;
• control the analyzer to sequentially analyze the reaction products acquired by the acquirer;
• control the pre-processor to perform a pre-process to be performed before an analysis of the reaction products by the analyzer;
• and
• control the pre-processor such that the pre-process for a second analysis to be performed subsequently to a first analysis is performed during the first analysis by the analyzer,
• the acquirer includes:
• a sample acquisition container having an inner flow path and having first and second ports that respectively communicate with the inner flow path,
• a first flow path that guides a reaction product produced by the reactor to the first port of the sample acquisition container, and
• a second flow path that guides a reaction product to outside of the sample acquisition container from the second port of the sample acquisition container,
• the pre-process includes a cleaning process of cleaning the acquirer,
• the pre-processor includes a cleaner that is configured to clean the first flow path, the second flow path and the inner flow path of the sample acquisition container by causing a cleaning liquid to flow through the first flow path, the inner flow path of the sample acquisition container and the second flow path as the cleaning process,
• the cleaner includes:
• a first switching valve provided in the first flow path, and
• a second switching valve provided in the second flow path,
• wherein the first switching valve is configured to be selectively switchable to a first state in which the reaction product is flowable from the reactor to the first port or a second state in which an inflow of the reaction product from the reactor to the first port is preventable and the cleaning liquid is flowable to the first port through the first flow path,
• the second switching valve is configured to be selectively switchable to a third state in which the reaction product is flowable from the second port to the reactor or a fourth state in which an outflow of the reaction product from the second port to the reactor is preventable and the cleaning liquid is dischargeable from the second port through the second flow path, and
• the controller is further programmed to control the cleaner to:
• switch the first switching valve to the first state and switch the second switching valve to the third state to acquire the reaction product from the reactor, and
• switch the first switching valve to the second state and switch the second switching valve to the fourth state to cause the cleaner to perform the cleaning process.
