Mg stands for the mass of the sample in the gas phase. As the sample is heated, volatile compounds enter the headspace of the vial. So the combination of the mass of the sample in the gas phase and the mass of the sample matrix is equal to the original mass of the sample: Mo=Mg+Mm. In order to calculate the Mass of the gas you would need to multiply the concentration of the gas and the volume of the gas: Mg=Cg*Vg.
Hi, in mass balance equation, is Mg mean volume of mass in gas phase?
