TPD/TPO equipped with Mass Spectrometer
Temperature programmed desorption/ Oxidation equipped with Mass Spectrometer is very useful to  characteristic of catalysts e.g. T of isopropylamine by following m/e= 41 and17  which provides acidity and acid stregth of the catalyst. It can also used for analysis of coke formation by TPO techniques by following m/e = 44.  This system can also be used for chemisorption of CO.
