Rigaku Corporation Temperature Programmed Desorption Analyzer TPD type R

For characterization of catalyst material, it is needed to examine the adsorption state by detecting components to be desorbed when a reaction gas is circulated through a sample with heat applied. Required also is to check the oxidation and reduction characteristics of the sample and look into the reactivities of substances adsorbed on the sample surface. The TPD type R has realized high-precision analysis of desorbed gas by adopting a gas circulation type holder and a skimmer type gas sampling system. EGA is an analytical technique in which the characteristics or amount of volatile products released by a substance are determined as a function of controlled temperature variation. EGA is typically used in materials science research and in the pharmaceutical industry to determine thermal stability, decomposition mechanisms, the nature of residual solvents and product safety. Thermal analysis allows the elucidation of microscopic information-such as chemical properties and crystal structure-allowing more precise determination of what kind of processes are occurring in the sample. The evaluation of thermal stability of polymeric and electronic materials, and recycling processing of polymers are socially important technologies, so there are increasing demands for improved EGA analysis methods.
