The testing site „Polymer Materials Analytics„ (PW) is competent under the terms of DIN EN ISO/IEC 17025 to carry out chemical tests of polymer material used in the pharmaceutical and food sector as well as chemical test of materials for contamination with PAH.
The testing site „Polymer Materials Analytics“ (PW) is concerned with organic trace analysis in rubber articles and articles of daily use on the basis of polymer materials. One focus is leachalbes/extractables analysis. Many polymer materials emit small amounts of additives needed for achieving certain physical and chemical properties when they are in contact with liquid media as for example drinking water or pharmaceuticals. Such additives are for example plasticizers, processing aids and anti-oxidants. Depending on the kind of polymer material and the liquid medium to which it is exposed a migration of the additives into the liquid medium takes places. Typical migrating additives from the group of plasticizers are phthalates while fatty acids are representative leachables of processing aids and substituted phenols of anti-oxidants. By means of High Performance Liquid Chromatography (HPLC) leachables/extractables with middle to high molecular weights can be analysed qualitatively and quantitatively down to the lower ppm range. By coupling of HPLC with a mass spectrometric detector a direct identification of substances is possible. A routine technique for identification of leachables/extractables with lower molecular weights is gaschromatography coupled with mass spectrometry (GC-MS). As containers, tubes, packagings or filters made of polymer materials get an increasing significance in the pharmaceutical and food industry due to their outstanding practical and chemical properties and have to meet particularly high demands concerning purity and compatibility, the area of leachables/extractables analysis is an important instrument for their quality assurance.
