Pyrolysis Gas Analysis:

Hydrocarbon Composition Analysis:
Identification and quantification of hydrocarbons produced during pyrolysis processes.

Impurity Analysis:
Detection and measurement of impurities such as oxygen, nitrogen, carbon monoxide, and carbon dioxide.

Gas Yield Determination:
Measurement of gas yield and composition to optimize pyrolysis process parameters and product quality.

The gases were identified as H2, CO, CO2, C4H6, CH4 and C2H6, with lower concentrations of other hydrocarbon gases and Sulphur gases, H2S, COS, SO2..

In pyrolysis-gas chromatography (PyGC) the fragments resulting chromatogram (pyrogram) are easily identifiable and give direct structural information about the material being pyrolyzed. Many polymers, polystyrene and polymethyl methacrylate for example, generate significant quantities of the monomer used in producing the polymer. For other materials, the pyrograms are more complex and serve as “fingerprints” which may be used to distinguish related materials for identification or for quality control. The pyrogram on the left was produced from a small sample of automobile paint, and could be used for competitor product analysis, quality control or in a forensic setting to help identify the car involved in a crime.The number of operator, factors which are innate to the sample materials, and those coming from the instrumentation.
