Automated Catalyst Characterization System - A catalyst characterization laboratory enclosed in one cabinet. The AutoChem II 2920 is a fully automated chemisorption analyzer that can provide your laboratory with the ability to conduct a comprehensive array of highly precise studies of chemical adsorption and temperature-programmed reactions. With this single instrument, you can acquire valuable information about the physical properties of your catalyst, catalyst support, or other materials. It can determine catalytic properties such as percent of metal dispersion, active metal surface area, acid strength, surface acidity, distribution of strength of active sites, BET surface area, and more. The AutoChem II 2920 performs pulse chemisorption, temperature-programmed reduction (TPR), desorption (TPD), oxidation (TPO), and reaction analyses and does it automatically. Features Powerful Windows operating and data reduction software Three gas ports (prep, carrier, and analysis) contain four inlets providing the capability to perform four-gas sequential experiments Four high-precision, independently calibrated mass flow controllers provide extremely accurate, programmable gas control With the CryoCooler option, analysis temperatures can be ramped over the range of -100 °C to 1100 °C Graphic reports for BET surface area, pulse chemisorption, heat of adsorption, and more. In addition, A full-feature peak editor and integration package is included with the AutoChem II. This easy-to-use package provides a rapid method for evaluating common temperature-programmed and dynamic adsorption data. 구성 및 성능 촉매 특성 분석 장비 PC(S/W) 사용예 촉매를 storage한 반응기에 gas를 주입하여 온도변화를 통한 TCD 측정 software 및 PC로 control. 특기사항 가스 사용 주의 한글 키워드 촉매 비표면적, 산화, 흡착, 탈착 및 환원 영문 키워드 TPR, TPO, TPD 장비의 원리 및 특징 - Dynamic gas flowing 방법을 사용하여 시료의 표면적 측정이 가능하며, 사용자의 온도 설정을 통해서 자동으로Desorption/Reduction/Oxidation 구현이 가능하며, 금속 분산도 측정을 위한 pulse chemisorption이 가능. - 시료에 일정량의 Gas를 인입하고 온도 변화를 주어서 반응된 Gas의 양을 TCD 로 측정 - Software 및 PC로 control
