System and method for automatically measuring total solid content

Abstract

Provided is a system and method for automatically measuring the total solid content. The system comprises a sample pretreatment container, an agitation device, a sample transference device, a sample heating container, a filtration device, a drying device and a control device. The sample pretreatment container is used for containing the sample solution waiting to be pretreated. The agitation device is fixedly or movably placed in the pretreatment container containing the sample. The sample transference device is fixedly or movably placed in the pretreatment container containing the sample, and transfers the sample solution to the sample heating container by absorbing force. The sample heating container is used for containing the sample solution to be heated and dried. The filtration device is located on a solution transference pipeline between the sample transference device and the sample heating container. The drying device is located at the periphery of the sample heating device or in the sample heating container. The control device is used for controlling the starting and stopping of the agitation device, the sample transference device and the drying device. The invention replaces the manual reagent preparation process. Peristaltic pump is used for transferring the sample during the whole process. An infrared device is used for determining the volume precisely, thus avoiding the errors brought by multiple types of measuring vessels.

Description

technical field [0001] The invention relates to an automatic analysis and measurement instrument, in particular to an automatic measurement system and method for total dissolved solid content. Background technique [0002] Measuring the total dissolved solids content in water samples is one of the routine experiments in the laboratory. After the quantitative water samples to be tested are filtered, they are transferred to a beaker and dried at 105°C or 180°C to obtain a solid residue, which is called dissolved. total solids. During the experiment, the experimenter needs to participate in steps such as manual measurement, filtration, transfer of the beaker and drying in a water bath. The operation process is too cumbersome, and human operation will affect the weighing instruments used, and it is easy to introduce human errors or system errors, causing the experimental results to deviate from their true concentrations. Therefore, automated instruments are needed to replace ma...

AI Technical Summary

Problems solved by technology

The operation process is too cumbersome, and human operation will affect the weighing equipment used, and it is easy to introduce human errors or system errors, causing the experimental results to deviate from the true concentration. Therefore, automated instruments are needed to replace manual operations.

[0003] At present, the only instruments that can be operated automatically are electric heating plates, which are used for drying samples, but such instruments do not have the functions of mixing, filtering and pipetting water samples.
