Several basic properties of MOFs and COFs like specific surface area and pore size must be determined in order to inform their subsequent application or to prove that the as-synthesized MOFs and COFs exhibit the expected property. Alfa Chemistry is the expert in the materials field and now is committed to the study and development of crystalline porous materials such as MOFs and COFs. Meanwhile, we have accumulated abundant experience in analysis and testing of material based on our comprehensive technical platforms and professional R&D team. Thus, we can provide highest quality basic properties test of MOFs and COFs to researchers around the world to promote their project research and development process.
Alfa Chemistry provides a broad array of basic property test for various MOFs and COFs materials. The following shows some test items of MOFs and COFs that is very important for its application and research.
※ Just a few of the common test items are exhibited above. If you have any other requirements, please contact us. We will serve you wholeheartedly.
Alfa Chemistry has mastered various test methods of MOFs and COFs characteristics abovementioned and has served numerous customers from all over the world. The following highlights some test methods are frequently used.
For determination of pore volume, pore size, pore size distribution and surface area, the following methods will be adopted.
Where n represents the absorbed content, nm refers to the mono-layer capacity, C implies an empirical constant, P stands for pressure and P0 represents the saturation pressure of N2.
Analogous to the BET modelling, the pore volume and pore size distribution can be extracted from the N2 adsorption isotherm by using the corresponding mathematical models.
For determination of magnetic susceptibility, the advanced magnetic measuring instruments based on SQUID will mainly be used.
