Descriptions:
KF106C Karl Fischer Titrator is a new developed micro moisture measurement and analysis apparatus with high-resolution color touch LCD, convenient and visual HMI and operability. The apparatus adopts high performance ARM processor, which has large data storage, fast and stable operation and outstanding anti-disturbance performance, has the advantages of high detection speed and high precision. The instrument has (i) self-diagnosis of trouble function, display and print the results when the test finished; (ii) measuring dynamic curve indicating function which makes the test more intuitive; (iii) large data storage function which could up to 1000 data records; (iiii) delay measuring function, which is very effective in the testing of lower moisture content of specimen. The instrument adopts the sliding touch stirring to control the speed; Moisture content calculation formula contains various algorithms that based on the volume and weight etc.; During the testing, people could modify the related parameters of the formula timely and will not affect the measurement value of moisture content which is convenient to the user.
The instrument adopts Karl-Fischer coulomb titration method to determine the moisture content of the liquid, gas and solid sample reliably. During the test, the instrument will make indirect measurement with corresponding sample injector of solid, gas and liquid to the solid of insoluble to the reagent and material that will pollute the electrode and affect reagent reacting, therefore, it is a kind of highly efficient, fully automatic analysis instrument which will be widely used in electric power, petroleum, chemical industry, medicine, railway, environmental protection, scientific research institutions and other industries.
Working Theory
Equation of Karl Fischer reagent and water is as follows:
I2+SO2+3O5H5N+H2O-2C5H5N·HI+C5H5N·SO3······(1)
C5H5N·SO3+CH3OH-C5H5N·HSO4CH3·············(2)
The reagent solution is composed by the majority iodine, pyridine with sulfur dioxide and carbinol etc. Iodine is formed through electrolyzing at anode. According to Faraday's Law, iodine is in the direct ratio with quality of electric charge. The equation is as follows:
2I¯-2e-I2······ (3)
From (1), molecules of iodine are equal to molecules of water. Put the sample in Karl Fischer reagent, water in the sample consumes iodine in the reagent. The instrument can display the consumption of iodine during the titration. The iodine consumption is in the ratio with the quantity of electric charge. The moisture content is decided by the quantity of electric charge. This instrument adopts automatic electrolysis current controlling system. The electrolysis current can be decided by the water content of the sample, the maximum is 400mA.
