Product Description
Introduction
The Measurment method of type ZKF1/ZKF1(A) Karl Fischer Moisture Titrator is the volumetric method, it is a special and a most reliable method, it has become a general analytical method in the world.
This instrument is applicable in many different fields, such as pharmacy, orgnatic chemistry, inorgnatic chemistry, petroleum chemistry, chemical fertilizer, agriculture pesticide, dyestuff, foodstuff etc...Due to the property of the substances be measured is different, so it is necessary to choose the solvent that can dissolve the substances be measured.
Characteristics
1. Accurate measuring Two-pin platinum electrode for endpoint detection and the titre will be changed from a great quantity to a small quantity automatically.
2. Airtight pipese Prevent the moisture, in atmosphere to permeate, and prevent the noxious gas to escape.
3. Easy to operate Easy to press the button these functions such as drawing and backing the reagent, measuring process, solvent in and waste liquid out etc. Be completed automatically.
The joints be used for connecting the bottles of reagent, solvent and waste liquid with the pipes conveniently.
Application reguirement
1. Temperature 10 -- 30 degree
2. Relative humidity ≤ 75%
3. Power 220V± 22V 50Hz
Principe of analysis
In Karl Fischer reaction, moisture in sample reacts with Karl Fischer reagent quantitatively. ZKF1/ZKF1(A) make the analysis based on the forllowing formula:
I2 + SO2 + 3C5H5N + H2O - 2C5H5NHI + C5H5NSO3
C5H5NSO3 + CH3OH - C5H5N. HSO4CH3
Add extracting solvent into the titration vessel, titrate moisture in the solvent with Karl Fischer reagent until solvent equilibrium be reached. Add a known amount of sample, titrate with Karl Fischer reagent having a known factor(mgH2O/ml) until the endpoint be reached. The Karl Fischer reagent factor be determined using water in standard. The moisture content of the sample be calculated then.
