Thermal desorption and pyrolysis direct analysis in real time mass spectrometry for qualitative characterization of polymers and polymer additives

Abstract: Rationale Direct analysis in real time mass spectrometry (DART‐MS) provides qualitative information about additives and polymer composition. However, the observed mass spectra are dependent on sampling conditions, in particular the DART gas temperature. This report describes the combination of a heated sample stage with DART‐MS for polymer characterization. Methods Industrial polymers with different compositions were examined by thermal desorption and pyrolysis (TDPy) DART. Samples were heated on disposable co… Show more

“…As already mentioned above peak intensity distributions of these adducts are quite different: While (CF 2 ) n CO 2 − , (CF 2 ) n COF − and (CF 2 ) n CO 4 − are limited to n < 15, (CF 2 ) n C 2 O 4 H − series is already present at 450 C and it can be traced up to n = 35 at 503 C. This difference may be explained by relative stability of reaction products: Calculated reaction energies of (14) and (16) are −464 and − 187 kJ mol −1 , respectively. The reaction (14) is highly exothermic and (CF 2 ) n COF − may undergo further fragmentation when the number of CF 2 units is large. On the other hand, the reaction (16) is less exothermic and further fragmentation of (CF 2 ) n C 2 O 4 H − might have been suppressed.…”

“…Although the method is effective for detection of polymer additives by thermal desorption, thermal decomposition of polymers would be incomplete and it is not sufficient for polymer characterization. Recently a sample heating device was developed for thermal desorption and pyrolysis (TDP) in combination with a DART ion source and this combination was shown to be very effective to analyze polymer pyrolysis products 12–14 . This study describes the first application of the TDP/DART MS for Nafion membrane.…”

“…The small volume of the SPME coating makes it well-suited to interface with DART [16] by using the high-temperature gas to desorb analytes from the fiber. Although DART has been used for qualitative characterization of polymers and polymer additives [17], the application of DART-MS to investigate exhibition case materials has not previously been assessed.…”
