Used QUANTACHROME Quantasorb BET #152367 for sale

QUANTACHROME Quantasorb BET is a laboratory equipment and accessory designed to accurately measure the surface area and pore size distribution of materials using the Brunauer-Emmett-Teller (BET) adsorption technique. This instrument is used to determine the total surface area and measure the physical properties of materials such as their porosity and surface energy. Quantasorb BET uses the adsorption of nitrogen gas to measure the surface area of various materials. It operates with the application of both low and high gas pressures. Under high gas pressures the instrument uses the BET method to measure the surface area of the sample being analyzed. A sample is placed in the adsorption chamber of QUANTACHROME Quantasorb BET and nitrogen is then introduced at a variety of known pressures. The amount of nitrogen absorbed by the sample is then monitored as the pressure is increased. This instrument also can be used to determine the pore size distribution of a material due to its application of both high and low gas pressures. Under low gas pressures, the instrument uses the Barrett, Joyener, and Halenda (BJH) method which measures the absorption of nitrogen within the pores of a sample. The nitrogen adsorbate is introduced at a variety of known pressures and the amount of nitrogen absorbed by the sample is monitored. A plot is formed to display the amount of adsorbate at a specific pressure. Quantasorb BET instrument also has a variety of user-adjustable settings to adjust the parameters of the experiment being conducted. These settings include the choice of nitrogen gas pressure, the temperature of the pollutant, the sample preparation method, and the type of sample being measured. These settings can be set to match the specific requirements of the experiment. Overall, QUANTACHROME Quantasorb BET is a versatile and accurate instrument for the measurement of surface area and pore size distribution of materials. The ability to adjust the parameters of the experiment ensures that the specific requirements of the experiment can be met. The accuracy of the BET and BJH methods for measuring surface area and pore size distribution makes Quantasorb BET an essential laboratory accessory for a variety of materials research projects.
