8 Measuring moisture contents of solid and liquid samples by using the Karl Fischer reaction. Hybrid Karl Fischer Moisture Titrator has world s first original features with convenient functionality, and high-speed, high-accuracy measurement using our Hybrid Titration Method. With our Electrolytic Factor Measurement System, factor measurement is possible without using pure water. This is a breakthrough product that innovates the Karl Fischer moisture titration instruments. This product complies with official methods of analysis specified by the ASTM, JIS (Japanese Industrial Standards), and as published in the European Pharmacopoeia and the United States Pharmacopeia. Single instrument and a single titration cell allow utilization of Volumetric/Coulometric/Hybrid Titration Methods. No cabled connections required between main control unit and titrator For safe operation Just one instrument with one titration cell is needed to perform volumetric, coulometric, and hybrid measurements. With high operability for the volumetric method, the requisite sealability for the coulometric method has also been realized. Integrated functionality greatly contributes to a compact installation and low maintenance requirements.

10 Hybrid Titration Method There are two Karl Fischer titration methods: volumetric titration method and coulometric titration method. Both have advantages and disadvantages. The volumetric titration method is suitable for measurement of high-moisture samples (1% or more), but not for low-moisture samples (ppm order). Meanwhile, the coulometric titration method is suitable for measurement of low-moisture samples (ppm order), but not for high-moisture samples (1% or more). This is because measurement time is rather long and if the sample quantity is reduced in order to shorten the measurement time, errors from weighing would affect the measurement results. Change level potential Coulometric titration method Volumetric titration method Potential Measurement time Detection electrode (Twin platinum electrode) The hybrid titration method highlights the advantages and covers address the disadvantages of both methods. The hybrid titration method runs both volumetric and coulometric titration methods in parallel. Once water content goes below a certain level, measurement will be performed using the coulometric titration method. The method automatically switches from the parallel running of volumetric and coulometric titration methods to the coulometric titration method only. The system runs the coulometric titration method when a sample includes only water content lower than the certain level. Inner burette Stirrer rotor Switching valve Titration nozzle Karl Fischer reagent Piston burette Volumetric Titration Method In the Karl Fischer reaction, water reacts with iodine and sulfur dioxide quantitatively in the presence of base and alcohol. H2O + I2 + SO2 + CH3 4CH3 After dehydrated solvent is put in the titration cell and the dehydrated state is achieved by titration using Karl Fischer reagent, the sample is added into the titration cell. Water content is determined by using Karl Fischer reagent of which the factor (mgh2o/ml) is pre-determined with the water-methanol standard etc. Titration proceeds by controlling the titration speed while detecting the polarization of the electric potential of the detection electrode.

H2O + I2 + SO2 + CH3 4CH3 1 In the coulometric titration method, iodine is generated by the electrolysis of the anolyte containing iodide ions. 2I e - 2 Once the generated iodine is consumed according to equation (1), the detection electrode detects the consumption of iodine and iodine is generated again by electrolysis according to equation (2). The generated iodine is proportional to the electric quantity according to the Faraday s law. The equation (1) shows that I2 reacts with H2O in the proportion of one to one. The electric quantity required for the electrolysis based on the principle as described above is converted into water content.

12 Model Name Remarks Evaporator ADP-611 CHK-501 Multiple Sample Changer Multi-sample evaporator for the coulometric titration method. Since heating temperature can be set for each sample, different kinds of samples can be set at the same time (24 samples). Connection tube (for Multiple Sample Changer) ( ) is required. (NON-CE) Together with Karl Fischer moisture titrator, this evaporator allows to measure the moisture content in powders or solid samples that cause side reactions and therefore cannot be titrated directly. The samples are heated and the vaporized moisture is carried into the titration cell by a carrier gas. The sample boat moves in a closed tube driven by a magnet. This makes it possible to perform reliable measurements of trace moisture eliminating the risk of contamination from atmospheric moisture. A patented scan mode automatically determines the optimal evaporation temperature based on the relation between released water and heating temperature. The heating tube is easy to be cleaned thanks to its simple structure. heating furnace sample inlet exhaust valve of purge gas ADP-513 ADP-512 ADP-512S ADP-344 Evaporator for Oil Sample Evaporator for Ores Evaporator for High Temperature Heat Extractor for Sugar Sample This unit heats and evaporates lubricant oil, grease, tar products, paints, and other viscous liquids.

Scan mode Japanese Patent no Time vs. Water MKH-710/2nd Hybrid Karl Fischer Moisture Titrator The scan mode automatically determines the optimum evaporator temperature. It is used when the vaporizing temperature of a sample is unknown or if the sample tends to thermal decomposition. In the scan mode, the temperature in the heating furnace is increased at a constant rate and the evaporated moisture curve is analyzed. The optimum evaporator temperature is determined based on the decay observed in the evaporated moisture curve.
