| Abstract: | The content of CO2 in the thermolysis preduct of electric machine's coils (epoxy glist powder) can be determined by the runaway gas instrument linked with the gas color spectrum device with the help of pressure balance back flow techhique. The analysis time is 12 minutes and the devection limit 5 ×10-3mg/L. The accuracy cv is 2. 82% and the recovery retio 98. 12%. |
