No.KCZ-13069 KEM Application Note KCZ-130 69Coulometric Karl Fischer titration Kyoto Electronics Manufacturing Co.,Ltd. Data No.ILA13-99051 Moisture measurement on 2-Propanol (Isopropyl Alcohol) -Summary- As the result of the feasibility study of the moisture measurement for 2-Propanol by MKC-520, agood repeatability was observed. Therefore, this measurement is judged possible. -Measuring instrument- -Measuring instrument- Main unit:MKC-520 Coulometric KF moisture titrator Electrode: M-713 Twin Platinum Electrode 98-103-0002 Inner burette (one chamber) 98-103-0002 Inner burette (one chamber) -Reagent- Anolyte: Coulomat AG -Measuring method- Preparation: (1) Put 150mL of Anolyte in the titration cell. (2) Pre-titrate it for dehydration. Measurement: (1) Take approximately 0.4g of the sample with the syringe and measure the moisture of it. -Equation- Moisture(ppm):((Data-BGxt-Blank)/(Wt1-Wt2)) -Ambient conditions- Temperature: 22.8°℃ Weather: Fine -Measurement parameter- -Printout data- 「TITR.PARA1 Method 1 Titr.
