AppNote 244: Pyrolysis GC-MS: Nylon and Nylon-Containing Products

Abstract

The GERSTEL PYRO system heats the sample using an advanced dual coil platinum wire that allows it to operate in a variety of pyrolysis modes including standard pulsed, sequential, fractionated, evolved gas analysis, and smart ramped pyrolysis. In addition, lower temperatures can be used to perform thermal desorption before pyrolysis. The unique heating system provides uniform sample heating and unmatched reproducibility. The system also has an integrated GERSTEL Cooled Injection System (CIS 4) inlet that can be used to cryofocus analytes in the inlet – or as a hot split interface for direct transfer to the column. The addition of a GERSTEL MultiPurpose Sampler (MPS) allows for complete automation of the analysis.

This study describes the use of the GERSTEL PYRO system in combination with the GERSTEL MPS robotic autosampler for analysis of nylon standards and common consumer products containing nylon polymers.
