These methods include gas adsorption, mercury intrusion, electron microscopy (SEM or TEM), small-angle X-ray scattering (SAXS), and small-angle neutron scattering (SANS). In 2010, the United States Dispersed Technology Corporation (DT) and the United States Conta Instruments also jointly developed the electroacoustic electro-vibration method, and the Occhio Company of Belgium developed the image method for large hole analysis. In general, each method has its application limitations in pore size analysis. ?

Gas adsorption is the most common method for different methods of pore size characterization, as its pore size measurement ranges from 0.35 nm to over 100 nm, covering all micropores and mesopores, and even extending to macropores. In addition, the gas adsorption technology is easy to operate and low in cost compared to other methods. If the gas adsorption method is combined with the mercury intrusion method, the pore size analysis range can cover from about 0.35 nm to 1 mm. Gas adsorption is also the best way to measure all surfaces, including irregular surfaces and the area inside the openings. ?
