Embodiment Construction

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] figure 1 It is a schematic diagram of the composition of the water quality analyzer involved in the present invention. like figure 1 As shown, the water quality analyzer of the present invention includes a multi-port valve 1 , a syringe pump 2 , a sample pool 3 and a sampling tube 4 for connecting the sample pool 3 and the multi-port valve 1 . The multiport valve 1 has one common port 11 and a plurality of connection ports 12 (eight in this embodiment), and the common port 11 can communicate with any one of the connection ports 12 by switching the multiport valve. The common port 11 is connected to the syringe pump 2, and the connection port 12 is connected to the sampling tube 4, various test reagents A to D, diluent, other devices 5, and the discharge tank 6, etc. respectively.

Abstract

The invention discloses a method for moistening and washing a water quality analyzer. The water quality analyzer comprises a flow path switching valve, a liquid feeding device and a sampling tube, wherein one public port and a plurality of connection ports are formed in the flow path switching valve; any one of the plurality of the connection ports can be communicated with the public port after being switched; the liquid feeding device is communicated with the public port of the flow path switching valve; the sampling tube is communicated with one of the connection ports of the flow path switching valve. The method for moistening and washing the water quality analyzer is characterized in that when samples of different concentrations are analyzed, after sample analysis is completed, and before sample analysis is started, parts to be moistened and washed are moistened and washed in the following modes: an analysis sample to be moistened and washed is divided into more than two parts, andparts to be moistened and washed are moistened and washed for times the same as a quantity of the parts. By adopting the method disclosed by the invention, the amount of an effluent can be reduced, and the treatment cost can be reduced.

Description

technical field [0001] The invention relates to a method for rinsing a water quality analyzer. Background technique [0002] When the water quality analyzer takes samples by using a system with valves and pumps, it is first necessary to rinse the water intake pipes, valves, etc. with the sample to be tested. [0003] Generally, the amount of the sample to be tested for rinsing is twice the volume of the place where rinsing is required. In order to minimize the influence of the last measured sample, it is necessary to increase the amount of sample to be measured for rinsing. However, although the influence of the last measured sample can be reduced if the amount of the sample to be measured used for rinsing is increased, the discharge amount of the waste liquid is correspondingly increased. Contents of the invention [0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a method for rinsing a water quality analyzer. The wa...
