What is bet used for?īet! Bet is a slang term of affirmation, agreement, or approval along the lines of “Cool!” or “I’m down!” It can also suggest doubt or disbelief: “Yeah, sure.” How does Bet instrument work? The technique is referenced by several standard organizations such as ISO, USP and ASTM. The BET (Brunauer, Emmett and Teller) theory is commonly used to evaluate the gas adsorption data and generate a specific surface area result expressed in units of area per mass of sample (m 2/g). The BET equation strictly describes a linear plot of 1/ vs. The BET equation (Equation 1) describes the relationship between the number of gas molecules adsorbed (X) at a given relative pressure (P/P 0), where C is a second parameter related to the heat of adsorption.
