TPD (also known as TDS or TPR) involves heating a sample while contained in a vacuum and simultaneously detecting the residual gas in the vacuum by means of a mass analyser. As the temperature rises, certain absorbed species will have enough energy to escape and will be detected as a rise in pressure for a certain mass. The TPD unit is used in the Thermal Characterisation of Catalysts (TPD) and for monitoring of on-site Temperature Programmed Reactions (TPR). 

 

The Mayura Analytical TPD unit is the first of its kind that is wholly manufactured in India. It is a highly efficient and economical model at a fraction of the cost of its nearest competitor. With a large temperature range of up to 10000C, our TPD unit is sought after by many research institutions.
