摘要: Abstract In the present work, reliability of responses obtained using an experimental TPD-MS system with actual chemical process occurring at reactor is investigated. The device operates in a flow helium normal pressure. probable existence fractioning phenomena was studied by comparing our to instantaneous pulses CO 2 and H . accordance results study, analysis evolved gases not significantly disturbed fractioning. order study distortions induced on trace recorded MS for each analysed, stimulus-response technique has been used. Instantaneous were used as probe signals. Analysis carried out means so-called dispersed model. dispersion moduli determined under different conditions, which allowed optimization working conditions achieve minimum distortion significance perturbations real TPD experiment discussed application principle additivity variances corresponding decomposition MgCO 3
