催化剂金属分散度及 TPR/TPD 化学吸附分析仪
Catalyst developers use this chemisorption analyzer to measure metal dispersion by pulse titration and to profile reducibility and acid sites by TPR, TPD and TPO. The furnace reaches 1100 °C at 0.1–50 °C/min, with 4–6 MFC-controlled gas lines. TCD detection is standard and senses 0.1 µmol H₂ uptake; an MS can be added.
