How is the amorphous content in the sample measured? The DVS device (DVS Intrinsic) can determine the amorphous content in a sample through two methods: 1) When the sample absorbs water or other solvents, its amorphous components form hydrates or solvent compounds in a stoichiometric ratio with water molecules or other solvents; in this case, the amorphous content can be determined from the change in mass, without the need for calibration using reference samples. 2) By taking advantage of the significant difference in adsorption properties between the crystalline and amorphous states, and through fitting using reference samples, the content of the amorphous phase in the material is determined.
