Thermogravimetric analysis (TGA)

P3,000/sample (P2,400 student rate)

Thermogravimetric (TG) analysis follows changes in the mass of the sample as a function of temperature and/or time. TG analysis also gives characteristic information about the composition of the measured sample, in particular the amounts of the various components and their thermal behavior. In addition, further measurements are possible such as kinetic analysis of thermal decomposition.
The identification of gases released directly from the sample or during thermal treatment cannot be performed just by thermal analysis, but by coupling a spectroscopic method such as Fourier-Transform-Infrared (FT-IR) spectroscopy is an excellent solution. IR spectroscopy is a classical technique, which depends upon the interaction of infrared radiation with the vibrating dipole moments of molecules. It gives, with the exception of homonuclear diatomics and noble gases, a characteristic spectrum for each substance.
