Objective
An extruder used for processing polyolefin experienced a build-up of an unknown material.
Analytical Strategy
Due to the critical nature of the application, every effort was made to be certain the techniques involved would identify the issue. For this reason, a variety of techniques were used including, LCMS, PYMS, Headspace GCMS, TGA and PIXE. The mass spectrometry techniques were used to identify the organic composition of the sample, while TGA and PIXE were used to determine the inorganic nature of the sample.
