3Flex: Surface and Catalyst Characterization
비표면적 및 기공분포에 대한 분석을 할 수 있는 기기로써, N2가스의 물리흡착을 이용하여 Meso/Microporous 물질의 surface area, pore size, pore size distribution, pore volume 등을 측정하고 BET, Langmuir, BJH, H-J, DFT, Mp, H-K, DR등으로 결과를 산출할 수 있다.
- Carbons, Zeolites, Silicas, Aluminas 등으로 Meso~Micropore 영역 측정
- 석탄, 탈황제, 촉매의 비표면적, pore크기 및 체적 등 측정
- 각종 소재의 기공분포측정
