Initial investigations using a Quartz Crystal Microbalance involved measuring the interaction between chloroform and myoglobin. As chloroform interacted with the myoglobin, the mass uptake of the film was measured. After equilibration, the mass of chloroform desorbing from the film was measured. Specific tubing was selected so that no interactions between the gas and tubing were appreciable. Calculations were performed to account for the pressure drop along the length of the tubing.
