Acquisition of a new pyrolyser-thermodesorber-GC-MS with direct introduction in mass spectrometry option


Pyrolysis coupled with mass spectrometry is a particularly well-suited technique for the characterization of complex compositions (polymers, copolymers, rubbers or other non-soluble products), additive analysis, reverse engineering. The system available at Certech is automated, very flexible and allows the pyrolysis of solids and liquids up to 1000 ° C, at speeds ranging from 0.02 to 100 ° C / s. The thermodesorption unit can be used sequentially with the pyrolyzer on the same sample, which allows to obtain pyrograms containing a maximum of information. The thermal decomposition products are analyzed by GC-MS. The mass detector is equipped with a direct introduction probe (DIP). This accessory allows the injection of liquid and solid samples that do not require chromatographic separation and without special preparation. The probe can be programmed with several ramps and heating rates from 0.1 to 2 ° C / s up to a maximum temperature of 400 ° C.
