Problems solved by technology
Most of the current commercial automatic dilution equipment is aimed at biological samples, the preparation capacity is small, the dilution is single-point, the accuracy needs to be improved (accuracy is less than 2%), the dilution range is narrow, the gravimetric method is more accurate than the volumetric method, and the price is expensive. And limited by the laboratory environment, it is not suitable for on-site testing

The present invention relates to a solution dilution method and system, comprising the following steps: (1) inputting the concentrations, target solution concentrations and volumes of different mother liquors; (2) according to step (1), automatically calculating the mother liquor volume and solvent required for dilution (3) Determine whether the liquid dosing unit needs to be cleaned, if so, perform step (4) after cleaning the liquid dosing unit; if not, perform step (5); (4) After cleaning the liquid dosing unit, perform step (5); ( 5) Absorb different mother liquors through the pipeline of the liquid dosing unit, and suck air between the mother liquors to make them spaced; (6) After outputting the mother liquor to the container, then output the solvent through the pipeline of the liquid dosing unit into the container, and mix evenly , to obtain a diluted solution. The dilution method of the invention can effectively reduce the consumption of the mother liquor, greatly reduce the cleaning times, and save cleaning water.
Description
technical field [0001] The present invention relates to the technical field of analytical chemistry, and more particularly, to a solution dilution method and system. Background technique [0002] At present, the solution dilution is mainly based on the traditional manual dilution method, and the automatic dilution equipment or devices on the market are mainly based on the two principles of volumetric method and gravimetric method. The traditional manual dilution method has high accuracy, but the glassware such as pipettes and volumetric flasks used must be qualified for metrological verification, and if many solutions with different concentrations, different volumes or wide concentration ranges are to be prepared, the There are many specifications of glassware, and the dilution time is also long. Most of the current commercial automatic dilution equipment is aimed at biological samples, the preparation capacity is small, the dilution is single point, the accuracy needs to b...
