instrument composition
-Electric furnace
Temperature range:
25°C~1500°C
Heat speed :
Maximum 200°C/min
*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

2-1-1. Principle
“Developed a theoretical model to evaluate the overall heat transfer coefficient, considering both conduction through the solid and heat exchange from the solid surface to the gas.”
An accurate determination of the geometrical parameters of the foam was considering the difference in the pore size and the measured value res
Characteristic of MOGS
1. Metal oxides possess electronic, chemical, and physical properties of high sensitivity to changes in their chemical environment.
2. The sensing properties of semiconductor metal oxide assures improved selectivity and stability
3. Their peculiar characteristics and size effects make them interesting for metal oxide gas sensors
The reason we take Nox as targe
일반 냉장고와 김치냉장고 차이점.
일반냉장고는 간접냉각방식을 택하고 있는데, 냉각된 찬바람을 공급해서, 온도가 떨어지면 냉각을 멈췄다가 온도가 상승하면 다시 냉기를 공급하는 방식입니다.
이러한 이유로 일반 냉장고는 문을 열면 냉기가 빠져나와서 온도가 올라가고, 문을 닫으면 다시
1. 실험목적
산촉매(제올라이트)에 대한 암모니아의 탈착현상을 조사함으로서 촉매의 특성에 대하여 알아보고, 가스크로마토그라피를 이용 pulse technique에 의해 탈착현상을 이해한다.
