Pulse thermal analysis: A new range of opportunities

Article abstract of DOI:10.1023/A:1010177300149

Pulse thermal analysis (PTA) is based on the injection of a specific amount of gaseous reactant into a carrier gas stream. PTA provides the following advantages compared to conventional TA: (i) quantitative calibration of the mass spectrometric signals allows increasing the sensitivity of TA measurements; (ii) monitoring of gas-solid processes with defined extent of reaction i.e. the reaction can be stopped at any point between pulses, enabling elucidation of the relationship between the composition of the solid and the reaction progress; (iii) simultaneous monitoring of changes in mass, thermal effects, composition and amount of gaseous reactants and products under pulse conditions.
