Micromeritics Gemini 2380

The Micromeritics Gemini 2380 is a high-precision analyzer designed for the characterization of the specific surface area and porosity of powdered and porous materials. The instrument operates on principle of physical gas adsorption (typically nitrogen) at cryogenic temperatures, enabling the measurement of specific surface areas as low as 0.01 m²/g. Utilizing an advanced twin-tube balanced design, the system automatically compensates for thermal gradients and variations in free space, thereby ensuring highly accurate and reproducible data. The software suite permits the evaluation of B.E.T. and Langmuir surface areas, determination of micropore volume via the t-plot method, and pore size distribution analysis based on the B.J.H. method. Consequently, this instrument is widely employed in materials science research across the fields of heterogeneous catalysis, pharmaceuticals, ceramics, and advanced functional materials.

Principle of work
The instrument measures the specific surface area of a powder samples by using B.E.T. method. Nitrogen gas is employed as the probe molecule and is exposed to a solid under investigation at liquid nitrogen conditions. Porosity of the powder sample is determined by the adsorption-desorption method using nitrogen as the adsorbent. The pore volume and the pore size distribution are determined according to the t-plot method and B.J.H. method. Before analyzing the samples, it is necessary to prepare them by removing moisture and other contaminants. The instrument measures a specific surface area greater than 0.01 m2 / g. The amount of sample required for analysis is about 2 cm3 (smaller tubes) or about 6 cm3 (larger tubes, for samples with a total surface area of less than 1 m2).
