Gravimetric sorption is a popular analytical method utilized for the determination of the rate of interaction between a gas and an either solid or liquid material. The gravimetric sorption technique works with a sample’s weight being continuously measured on a microbalance as gas pressure is modulated under a constant temperature. Sorption update is established based on the measured changes of weight.
