SUCCESSIVE INJECTION/ANALYSIS SYSTEM FOR NITROGEN COMPOUND MONITORING TAILORED TO INLAND FARMING

摘要

The present invention relates to a successive injection/analysis system for nitrogen compound monitoring tailored to inland farming, the system being provided to be able to monitor nitrogen compounds remaining in a water tank of a farm in order to manage the farming environment of the farm. A successive injection/analysis system for nitrogen compound monitoring tailored to inland farming according to the present invention comprises: a multi-port valve having multiple ports; a sample supply portion connected to the multi-port valve so as to supply a sample of an inspection target; a reagent supply portion connected to the multi-port valve so as to supply a reagent which is to be mixed with the sample such that detection of nitrogen compounds proceeds; a carrier water supply portion connected to the multi-port valve so as to supply carrier water; a photodetection unit connected to the multi-port valve so as to provide a passage such that an inspection substance, which is a mixture of the sample and the reagent, passes along same, the photodetection unit being configured to detect the concentration of nitrogen compounds in the inspection substance; and a syringe pump connected to the multi-port valve so as to inject the sample and the reagent or the carrier water into the multi-port valve or to withdraw same.
