The GERSTEL PyroVial performs pyrolysis procedures at temperatures up to 800 °C in a dedicated sample vial. Less volatile and thermally labile pyrolysis products can be taken up in a suitable solvent for subsequent GC/MS or LC/MS determination – or for analysis using other techniques.
Volatile pyrolysis products can be sampled directly from the Headspace for GC/MS determination. Placing a sample into the reaction chamber is simple and the pyrolysis process is fully automated based on the GERSTEL MultiPurpose Sampler (MPSrobotic).
PyroVial can be used as a micro-scale reaction chamber, the gas phase can be replaced with an inert gas or a reactant as needed. Food preparation processes, such as the Maillard reaction, can be simulated in micro-scale and the formed flavor compounds determined. Pyrolysis of polymers, for example those based on polar acrylic resins, can be followed by HPLC determination of the reaction products. Reagents or catalysts can be added before the pyrolysis step, enabling the simulation of complex industrial processes.
