Melting or phase transition of the sample in terms of heating or cooling evaluated in molecular level

Differential Scanning Calorimetry(DSC) or Thermo Gravimetric Analysis(TGA) is generally used as an evaluation method for thermophysical properties such as melting or phase transition of the sample. In addition, combination with X-Ray Diffraction(XRD) is sometimes used for the multiple evaluation of thermophysical properties and crystal structure. Jasco’s IR microscopes IRT-5000 and 7000 combined with the heating system MHC-5000 enable to have an integrated approach to the geometry change in molecule itself, or the thermopysical properties and the observation image. It can uniformly heat or cool the measurement area in IR microscope because the measurement area is much smaller than FTIR, assuring high accuracy measurement. You can easily control the temperature and the measurement conditions by interval measurement program of temperature through the PC. Scanning of sample image is available with the sample measurement at the same time.

Using the system of IRT-5000 with MHC-5000, benzoic acid was heated from 100C up to 150C with ramping rate of 2C per minutes and IR spectra were obtained with 0.5C intervals.
