sample happens at about 200 °C corresponding to an exothermic peak at about 214 °C in DTA curve. In MS curves of the pyrolysis products, there are the peaks of the species: SC(NH 2 ) 2 ( m / z = 76), CS ( m / z = 44), S ( m / z = 32) and NH 2 ( m / z
A new method for thermal analysis
Ion-attachment mass spectrometry (IAMS)
ionization by high-energy electrons, IAMS preserves the profiles of the product molecules much better, allowing their detection as adduct ions without any fragmentation. Among the pyrolysis products of polycarbonates, BPA may be of most concern [ 20
stage occurs in the temperature range of 300–370 °C. In this stage, the mass loss is very fast and significant. Most of pyrolysis products are produced in this stage. Referring to the literature, glucose is one of the major products, together with all
decomposed ligand part from the complex (Remaining mass% obs./calc., 38.27/38.67). A loss has been observed at 500–635 °C which corresponds to a mixture of metal oxide as an ultimate pyrolysis product (Remaining mass% obs./calc., 22.03/21.26) ( Fig. 1
the instantaneous heat of combustion of the flowing gas stream is measured by oxygen consumption calorimetry, which is subsequently used to determine the heat of combustion of the pyrolysis products. For this method, small polymer samples (1–10 mg
increases the thermal stability due to the reduction of pectin and hemicellulose component of hemp. Del Rio and coworkers [ 37 – 39 ] studied hemp lignin by pyrolysis-GC/MS and established that guaiacyl derivatives dominate among the pyrolysis products
