Description

technical field [0001] The invention relates to a concentration device and method, in particular to an online automatic calibration concentration device and method. Background technique [0002] When concentrating a liquid sample, in order to realize the automatic concentration of the liquid sample, it needs to go through the process of adding liquid, concentrating, and constant volume. The sample container used in the concentration process is mainly glass. Because the glass container is affected by processing accuracy and other reasons, it is difficult to achieve good consistency. Therefore, if you want to constant the volume of the liquid sample in the glass container, it is necessary to The container is calibrated. At present, the calibration of glass containers can be achieved by means of marking lines and sensing liquid level, but both of these methods have great disadvantages. Among them, the engraved line method is difficult to realize automatic processing because t...

AI Technical Summary

Problems solved by technology

The calibration process of the container is only carried out once at the factory, and it is difficult to calibrate it later, and the container used in the calibration process is difficult to be consistent with the actual container, especially the glass container. Due to the inconsistency of glass container processing, the same volume The liquid level of the same volume of solution in the same glass container is not exactly the same, and it is often difficult to achieve accurate quantification

During the calibration process, only a single volume calibration can be achieved due to the fixed position of the liquid level sensor

The method has poor adaptability and cannot be calibrated again after changing the container
