摘要
An in-situ analyzer for nutritive salt and a nutritive salt content analysis method. The analyzer comprises a microprocessor, drive components, a multi-way valve (5), an injector, a colorimetric detector (11), a mixing ring (12), a sample pipeline, a pure water bin, a standard solution bin, and various reagent bins. The injector, the colorimetric detector (11), the mixing ring (12), the sample pipeline, the pure water bin, the standard solution bin and various reagent bins are correspondingly connected to ports of the multi-way valve (5). The microprocessor is sequentially connected to a first motor driver and a first motor and then is connected to an injection pump (6) of the injector. The microprocessor is sequentially connected to a second motor driver and a second motor, then is connected to the multi-way valve (5), and controls ports in the multi-way valve (5) that is connected to the injector, to be in sequential communication with other ports in the multi-way valve (5). The colorimetric detector (11) is connected to the microprocessor.
