Embodiment 1

[0056] An automatic sample injection dilution method is composed of a sample injection process, a back pumping process and a dilution process.

[0057] Among them, the sampling process includes but is not limited to the following steps:

[0058] A101. Multi-way valve group 1 opens the corresponding sampling channel valve, and at this time all other channel valves are closed;

[0059] A102. Start the reverse rotation of the peristaltic pump 2 to pump the object to be sampled into the metering tube 3;

[0060] A103. After the liquid level pumped into the metering tube 3 reaches the specified liquid level indicated by the liquid level sensor 4, stop the peristaltic pump 2 and close the sampling channel valve of the multi-way valve group 1;

[0061] A201. Open the injection valve 6, and at this time all other channel valves are closed;

[0062] A202. Start the peristaltic pump 2 to rotate forward, and discharge the sampling object in the metering tube 3 into the sample chamber; ...

Embodiment 2

[0089] This embodiment is basically the same as Embodiment 1, the difference is that a plurality of liquid level sensors 4 can be set on the metering tube 3, so as to realize the dilution of various dosages and various ratios, such as figure 2 shown.

Abstract

The invention provides an automatic sample injection diluting method. The method includes the steps that an object of the appointed dosage and to be diluted and diluent are fed into a sample chamber; a part of mixed liquid in the sample chamber is reversely pumped to be drained; the remained mixed liquid in the sample chamber is fully reversely pumped to a metering tube; the mixed liquid in the metering tube is metered again, and the mixed liquid is drained into the sample chamber after being metered. Test results show that the sample injection error additionally introduced by primary dilution is controlled to be within + / -0.8%, and the sample injection error additionally introduced by secondary dilution is controlled to be within + / -1.5%.

Description

technical field [0001] The invention relates to an automatic sample injection dilution method, which is particularly suitable for automatic sample injection occasions requiring repeated multiple dilutions and large-scale dilutions, and can be widely used in the technical field of water quality monitoring (or detection). Background technique [0002] In terms of automatic injection dilution, the current routine practice is: [0003] 1. First inject the specified dose of sample to be diluted and the specified dose of diluent into the sample chamber; [0004] 2. Then extract the specified dose of mixed solution from the sample chamber; [0005] 3. The remaining mixed solution in the sample chamber is the final diluted sample. [0006] Restricted by pipeline layout and component structure, the pipeline between the control valve entering and leaving the sample chamber and the multi-way valve group (hereinafter referred to as "pipeline") is often relatively long. When the mixed...
