Product Description Product DescriptionCoulometric Titration Method Coulometric Karl Fischer TitratorCoulometric Titration Method is for Precise Measurement.The Coulometric Karl Fischer Titrator is mainly usd for measuring very low water content (less than 2%) in liquid and gaseous samples. It is used to accurately test trace water content in various liquid, solid and gases. And it is widely applied to petroleum, chemical engineering, pharmacy, electricity, scientific research, education department and so on.Product ParametersDisplay modeEnglish color LCD displayMeasurement range3 micrograms of water to 200 milligrams of water. Water content range: 1 ppm to 100%Resolution0.01 micrograms of waterElectrolysis speedup to 2.4 mg water/minElectrolytic current0 ~ 430 mAAmbient temperatureRecommended room temperature ~ 40 °C Ambient humidity: ≤ 85%PowerAC 220V ± 10%.Features1.Intelligent Determination2. Easy Operation3. Background Compensation4. Rotating Speed Control5. End Point Indication6. Perfect Calculating Function7. Automatic Date Data StoragePrincipleThe measuring principle used in this instrument is the Karl-Fischer Coulomb method. The principle is based on the fact that when water is present, iodine is reduced by sulphur dioxide, and in the presence of pyridine and methanol, pyridine iodine and methyl pyridine thioate are formed. The reaction formula is:I2+SO2+3C5H5N+H20→2C5H5N·HI+C5H5N·SO3 ......................(1)C5H5N·SO3+CH3OH→C5H5N·HSO4CH3 ....................................(2)During the electrolysis process, the electrode reaction is as follows:Anode: 2I--2e→I2 .......................................................................(3)Cathode: 2H++2e→H2↑.............................................................(4)The reagent solution used is a mixture of predominant iodine and pyridine-doped pyridine, methanol, etc., and iodine is formed on the anode by electrolysis, and iodine is reacted with water to form hydroiodic acid until all the water has been reacted. The end of the reaction was detected with a platinum electrode.According to Faraday's law, the formula for calculating the moisture content in the sample is obtained:.....................................................................................................(5)Where: W - moisture content in the sample, in micrograms Q--Electrolysis power, unit: millicoulombCalculated by the instrument, the moisture content of the tested sample is directly displayed on the display. The instrument uses an electrolysis current automatic control system. The size of the electrolysis current can be determined according to the moisture content of the sample, up to 430 mA.This instrument uses Karl Fischer (Coulomb method) reagentElectrolysis Cell Structure and Assembly:(1) Large pool bottle (anode chamber) (2) Measuring electrode (3) Drying tube (4) Electrolytic electrode (cathode chamber) (5) injection plug (6) magnetic stir bar (7) electrolytic cell sealing plugAccessories:No.NameQuantity1Main Unit1 Set2Electrolytic cell1 PC3Electrolytic electrode1 PC4Measuring electrode1 PC5Drying pipe1 PC6Gasket10 PCS7Vacuum grease1 Box8Power wire1 PC9Magnetic stirring rod1 PC100.5 Microliter sample injector1 PC1150 Microliter sample injector1 PC12100 Microliter sample injector1 PC131mL sample injector1 PCDetailed PhotosPackagingOur product packaging has been proven over the long term and we usually have plywood boxes or cartons with trays.
