Abstract

The invention provides a urea analyzer. The urea analyzer comprises a controller, a first sample injection pipeline, a second sample injection pipeline, a third sample injection pipeline, a fourth sample injection pipeline, a water bath device, a cooling cup, a detection piece and a waste liquid barrel, the first sample injection pipeline, the second sample injection pipeline and the third sampleinjection pipeline are correspondingly provided with a first sample injection pump, a second sample injection pump and a third sample injection pump, the fourth sample injection pipeline is provided with an air pump, the end part of the first sample injection pipeline is connected with a sample injection arm, a reaction vessel is arranged in the water bath device, the first sample injection pipeline is connected with the reaction vessel and the waste liquid barrel respectively through a multiport valve, the reaction vessel is communicated with the cooling cup, the cooling cup is connected withthe detection piece, the cooling cup is connected with the waste liquid barrel, the controller is in communication connection with the first sample injection pump, the second sample injection pump, the third sample injection pump, the multiport valve and the sample injection arm. The urea analyzer solves the problems in the existing urea analysis that the manual detecting and analyzing wastes time and labor and the large detecting quantity of samples easily causes large experimental error.

Description

technical field [0001] The invention relates to a urea analyzer and a urea analysis method using the urea analyzer. Background technique [0002] At present, there are two types of instruments for automatic detection and analysis of urea content in water on the market. One is a small, rapid detector. This instrument is easy to carry and can be taken to the sampling site for rapid detection. However, this instrument does not perform detection according to the national standard method. The accuracy of the data used in the laboratory cannot meet the requirements; the detection using the national standard method requires boiling water baths, cold water baths, manual timing, manual liquid addition, and manual color comparison, which is not only time-consuming and laborious, but also easily produces errors when the sample volume is large. lead to large experimental errors. Contents of the invention [0003] The invention provides a urea analyzer, which solves the problems in th...
