Digital buffering solution distributing system and method

Abstract

The invention discloses a digital buffering solution distributing system and method, and relates to the technical field of liquid distribution. The system comprises a circulating pipeline, a control subsystem and a control end, wherein the circulating pipeline is used for inputting liquid for adjustment and a mother solution, and the control subsystem comprises a digital sensor and an executor which are arranged on the circulating pipeline. The liquid distributing method based on the system includes the steps of detecting index real-time data of adjusted liquid through the digital sensor, feeding back the data to the control end, comparing the index real-time data of the adjusting liquid with stored index target data through the control end, judging whether the index real-time data and theindex target data are matched or not, controlling the executor to act, and outputting the adjusted liquid with the index real-time data meeting the index target data. Acidity and alkalinity data of the digital sensor expect an electric conductor and other environment parameter values are transmitted to the control end, corresponding conductivity data and acidity and alkalinity data are selected for judgment by comparing all environment parameters, and the liquid distributing accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of liquid preparation, in particular to a digital buffer liquid preparation system and method. Background technique [0002] Buffer solution refers to a mixed solution composed of weak acid, weak base and their salts, which can offset and reduce the influence of external strong acid or strong base on the acidity of the solution to a certain extent, so as to keep the pH value of the solution relatively stable. [0003] The traditional buffer solution preparation method is to weigh the weight of the required sodium chloride salt by the operator, use a graduated cylinder to measure pure water to dissolve and prepare, and put the final product into the liquid storage tank. Due to the time-consuming preparation process of this method, the solution cannot be prepared and used immediately, which easily causes the property of the solution to change during storage. [0004] In order to solve the above problems, the ...

Problems solved by technology

However, conductivity detectors traditionally only transmit one conductivity data, but in fact the conductivity data will be affected by other environmental parameters such as temperature and change, therefore, it will cause a deviation between the detected value and the actual value. As a result, wrong instructions are given to adjust, and the final solution results are biased
