RoHS 3 Phthalate Calibration and Reproducibility Study by IEC 62321-8 Standard Method

Materials being investigated by thermal sampling techniques such as pyrolysis are frequently polymeric, but they may also have volatile and semi-volatile contaminants and additives. When using pyrolysis- gas chromatography, these non-polymeric constituents produce some of the most significant peaks in the chromatogram. It has become common to perform two or more analyses on the sample at increasing temperatures, to remove the additives before pyrolysis. Often, analysis of the polymer structure is less important than the nature and amount of additives present, especially those additives known to be hazardous.
