CDS heeft nieuwe app notes gepubliceerd over ftalaat kalibratie en de reproduceerbaarheid met behulp van een IEC-norm methode. Materials being investigated by thermal sampling techniques such as pyrolysis are frequently polymeric, but 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. In some instances, however, analysis of the polymer structure takes a back seat to the nature and amount of additives present
