“…These specialised techniques can contribute to the exact unravelling of the thermal degradation pathways, mainly by identification of the degradation products. Thus, investigation of thermal stabilities has already been performed by coating the ionic liquid in fused silica capillaries which are heated and monitored by FID or mass spectrometry (MS), 30,31,83 as well as by pyrolysis-GC, 72,99 headspace GC/MS, 10 pyrolysis-MS, 32 TGA-MS, 9,61,65,100 and thermal desorption mass spectroscopy (TDMS). 35 Although TGA-MS is a very powerful method, it should be noted that the absence of molecular ions does not necessarily exclude vaporisation, since the transfer of TGA to MS and pressure differences herein involved hinder the detection.…”
