Curie-point pyrolysis. (Instruments).

The Pyromat Curie-point pyrolyzer coupled with a GC/MC system allows users to load up to 24 samples for unattended analysis. All parameters such as temperature, pyrolysis time and GC conditions, can be defined for each sample, if required. The Curie-point pyrolyzer can be installed or removed from the GC in just a few minutes, according to the company. Despite the pow-er of modern analytical instruments techniques of analysis such as gas chromatography and mass spectrometry, one of the most important challenges remains that of sample preparation, especially for non-volatile, insuluble materials and chemicals, according to the company. The advantage of the Curie-point pyrolyzer is the use of ferromagnetic material which heats up in a very short time inside a magnetic field to a defined Curie-point temperature. Pyrolysis temperature may be controlled by selection of the composition of the sample carrier. Through the selection of different alloy compositions, Curie-point temperatures can be provided from 160-1,040[degree]C in ca. 15 degree steps. Following pyrolysis, the fragments are transferred by the carrier gas into the gas chromatograph for separation and detection. Applications include polymers, copolymers, elastomers, synthetics and rubber. (GSG Mess- und Analysengerate, Vertriebsgesellschaft mbH, Im Technologiedorf 9, 76646 Bruchsal)
