Model
Quanta chrome, Autos orb iQ2 by Aton Paar
Features
Phys sorption-Surface area of 0.01 m 2 /g and upwards can be accurately determined using nitrogen at liquid nitrogen temperature.
Chemisorption-Chemisorption is used primarily to evaluate quantitatively the number of surface active sites which are likely to promote (catalyze) chemical reactions. Both static adsorption isotherms and dynamic pulse titrations yield monolayer uptake, metal area, nanocluster (crystallite) size and active metal area of heterogeneous catalysts. Isothermal results can be used to map surface energetic heterogeneity via heat of adsorption calculations.
Other Options
Vapour Sorption
TPD/TPR/TPO
Chemi Batch
Applications
- BET surface area (single and/or multipoint)
- Langmuir surface area, adsorption and/or desorption isotherms, pore size and surface area distributions, micropore volume and surface area
- Mapping surface energetic heterogeneity via heat of adsorption calculations.
