Nylon is well known polymer material as an aliphatic polyamide. There are several types of nylon such as nylon-6, nylon-6,6, nylon-6,10 and nylon-6,12. Though many analysis methods are used for identification of polymer structure, e.g. FT-IR, NMR, DSC, TG-DTA and pyrolysis-GC/MS, it is difficult to distinguish the nylon types easily due to their structural complexity. DART-MS is one of the powerful methods for the rapid analysis of mixture. However, this method is not suitable for polymer analysis since the polymer is difficult to volatilize. To overcome this weak point, we developed the temperature rising device combined with DART-MS system. The nylon types were determined rapidly by their pyrolysis profiles.
