Kyoto Electronics Manufacturing Co., Ltd.Data No.LA47-07251 No.EKCR-07273 KEM Application Note No.EKCR-07273 Coulometric Karl-Fischer Titration Moisture of N-66 polymer -Summary- Checked the possibility of measuring moisture of N-66 polymer in combination of MKC-520with ADP-511S, and good repeatability was obtained. -Measuring instrument- Main unit:MKC-520 Coulometric KF moisture titrator Option: ADP-511SEvaporator Electrode: M-713 Twin platinum electrode #433-0006Inner burette ·Reagent- Anolyte: Coulomat AG Catholyte: Coulomat CG Carrier gas: Nitrogen -Measurement method- Preparation: (1) Fill the titration cell with the anolyte and inner burette with the catholyte. (2) Pretitrate for dehydration. (3) Connect MKC-520 with ADP-511S and set the nitrogen flow at 200mL/min and theevaporation temperature at 200°℃. Measurement: (1) Place 1g sample in the sample boat and measure for its moisture. -Equation- Moisture (ppm): ((Data-Driftxt-Blank)/(Wt1-Wt2))xF Data: Measured water content (ug) Drift : Drift before measurement (ug/s) t: Measuring time(s)Blank : Blank value (ug) Wt1 : Tare including sample weight (g) Wt2 : Tare including residual weight (g) F:Factor(1.00) -Standard method- Karl Fischer method .Ambient conditions- 京都电子工业株式会社-可睦电子(上海)商贸有限公司上海市漕溪路222号航天大厦北楼902室电话:021-54488867 电邮: kemu-kem@163. com网址: http://www.kyoto-kem.net.cn -Measurement parameter- -Printout data- [Titration1 Method 4 Titr.
