Pyrol AB

The core competence of the Swedish company Pyrol AB lies in the pyrolysis of complex samples. Pyrolysis is the thermal decomposition of a material in an inert atmosphere, i.e. without the presence of oxygen. Pyrolysis allows a non-volatile material to be analysed in a gas chromatograph by examining the pyrolysis products, often by mass spectrometry. The samples may be insoluble, dark or inhomogeneous and may contain synthetic and natural polymers, such as vulcanised rubber, resins and composites. Paper, coal, textiles and paints are examples of materials that are successfully analysed by analytical pyrolysis. Different pyrolyzers use different heating methods, which in turn determines which temperature gradients and heating programs are possible. In the pyrola-pyrolysis systems, the sample is placed directly on a platinum thread which is heated by a strong current pulse. This offers maximum flexibility and possibilities that are not available with other systems. The same sample can be pyrolyzed repeatedly with short heat pulses, with GC running between the individual pulses. This facilitates interpretation and provides new insights when analyzing complex samples. The result of many years of research and development are particularly sophisticated systems for pyrolysis.
