Thermal analysis system enables selective GC/MS analysis of polymers by pyrolysis, thermal desorption/pyrolysis, and evolved gas analysis
Mandel Scientific introduces Shimadzu's PY2020 thermal analysis system for the Shimadzu QP series GC/MS instruments.
The PY2020 system enables selective GC/MS analysis of polymers by pyrolysis, thermal desorption/pyrolysis, and evolved gas analysis (EGA).
Pyrolysis can be used for macromolecular and other nonvolatile components.
For pyrolysis applications, the sample cup free-falls into the furnace where the sample is instantly pyrolysed with excellent reproducibility.
The GC separates the fragments and the MS identifies them.
Thermal desorption pyrolysis allows analysis of volatile compounds such as residual solvents, monomers, as well as antioxidants and stabilisers.
For thermal desorption analysis, a plunger lowers the sample into a micro furnace at 40C and the temperature is programmed up.
Once thermal desorption analysis is complete, the sample is taken out of the furnace, the temperature is raised to 600C and the sample cup is then dropped into the furnace for pyrolysis.
Sample cups can move in or out of the furnace for both thermal desorption and pyrolysis.
Evolved gas analysis (EGA) allows on-line MS analysis of compounds over a wide programmed temperature range.
Any desired zone of the EGA thermogram can be automatically collected as a heart-cut and introduced to the GC/MS for further analysis. The Shimadzu PY2020 thermal analysis system for GC/MS is available with a 48-place autosampler, which can reduce workload while improving productivity and reliability.
