Description
Technical field
The invention belongs to analysis Instrument equipment technical field, specifically just relate to a kind of can the device of moisture in measurement of species automatically.
Background technology
When carrying out elemental analysis, sometimes need the content of micro free water and water of crystallization in measurement of species, nineteen thirty-five, Ka Er Fischer proposes the method measuring moisture with non-aqueous solution reagent, i.e. I
2-SO
2reagent method.This method is in fact utilize chemical reaction to measure liquid water content, is applicable to the measurement of micro free water and crystal water content in most of organism and inoganic solids, liquid chemical product.Traditional measuring method according to this principle adds titrant by being with the standard of stopcock to move liquid glass tube, and whole process speed is slow, low precision.Piston transfer pipet after improvement eliminates lag-effect, operate quicker, accurately, the resolution of mechanical piston transfer pipet is 1/10000 or higher of traditional graduated cylinder, the charger of autotitrator is adopt Microprocessor S3C44B0X mostly simultaneously, motor drives the piston of buret, controller is utilized to change the deviation between preset value and actual measured value into control signal, control instrument automatic liquid-feeding, but nonetheless, for the liquid feeding of solvent, the current equipment of the processes such as discharge opeing also needs manually to carry out, not only add insecurity, add Measuring Time simultaneously, reduce and measure efficiency and measurement accuracy energy.
Summary of the invention
Technical barrier to be solved by this invention needs manual operation for existing moisture measurement instrument in liquid feeding, discharge opeing operation, security performance is not good, add the technological deficiency of Measuring Time, the device of automatic measurement moisture provided by the invention, achieve micro free water and crystal water content in material and measure whole-course automation control, improve the security of measurement, save Measuring Time.
