Problems solved by technology

[0014] However, the above-mentioned laboratory sampling steps need to manually introduce reagents and cleaning liquids. Such human operations require buttons and machine interaction. Not only the operation steps are cumbersome, but also the obtained test data needs to be judged and read, resulting in test err

Abstract

The embodiment of the invention discloses a method and device for detecting the automatic sample injection of a laboratory liquid. The method disclosed by the embodiment of the invention comprises the following steps: controlling a microprocessor to enable a driving pump to enhance the positive pressure or negative pressure of a pipeline by extracting the gas in a connecting pipe and a cuvette; finishing the steps of sampling color comparison, liquid drainage, moistening and cleaning under the condition that no manpower participates in the operation; and regulating and controlling the on-off action of the corresponding valves when each operation is carried out. In the embodiment of the invention, the testing course is simple and rapid; and moreover, the control of the microprocessor is matched with the slow liquid injection and air exhaust action of the driving pump and the accurate monitoring of a liquid height detector for the liquid injection height of the connecting pipe, thereby overcoming the defects of air bubbles and water blockage because of the existing artificial liquid pouring and realizing the purposes of greatly reducing testing errors and reducing reagent water source waste.

Description

technical field [0001] The invention relates to the technical field of laboratory liquid detection, in particular to a laboratory liquid automatic sampling detection method and device. Background technique [0002] Laboratory liquid testing plays a vital role in formulation related industries. [0003] The accuracy of liquid testing is one of the most important measurement qualities in liquid testing in laboratories. Taking the existing laboratory silicate liquid sampling steps as an example, combining figure 1 The description of the operation steps, such as figure 1 As shown, the existing laboratory silicate instrument comprises a sampling cup 104, the upper end of which is open to the inside for introducing sample liquid or clear water, and the bottom of the sampling cup 104 is respectively connected to the colorimetric cell through a pipeline. 102 is connected with the guide tube 103, and the top of the colorimetric cell 102 is connected with the guide tube 103 through ...
