BET-5 specific surface area tester uses nitrogen adsorption dynamic method to determine the specific surface area of powders. It has 4 working analysis stations and can test 4 samples at the same time. It is suitable for production enterprises with large output and many varieties.
Analysis range: 0.0005m2/g~unlimited; high test accuracy and good reproducibility.
Using dual-source dynamic gas chromatography, helium as carrier gas and nitrogen as adsorbed gas as test gas, the solid surface of different samples is analyzed, and the specific surface area of powders, particles and other materials in various industries can be quickly tested.
Specific surface area analysis of various powders and particles, such as graphite, lithium cobalt oxide, nickel hydroxide, lithium manganate, lithium titanate, lithium carbonate, pharmaceutical powder, catalyst, adsorbent, cement, ceramic raw materials, etc.
