In the present paper, significance of gas-phase chemical reactions occurring in thermal analysis furnace is evaluated. Free radical species form as a result of biomass thermal decomposition and may give rise to chain reactions. Gas portion emitted by the sample analyzed flows to detector (mass spectrometer in our study) in finite time interval, so chemical reactions may change its composition. Quantitative assessment of this change was made based on data about amount of active species that may initiate...
