Large volume pyrolysis
More sample material for microplastic analysis.
The Chromtech furnace pyrolyses samples in large ceramic crucibles. The larger sample volume supports a representative study of heterogeneous materials. Automatic crucible positioning and pneumatic locking ensure reproducible conditions.
A heated transfer line leads the pyrolysis products to a sorbent in the OPTIC liner. After thermal desorption, gas chromatographic separation is carried out using mass spectrometry (GC-MS) or tandem mass spectrometry (GC-MS/MS). Coupling with a thermogravimetric analyzer is not required.
Polydimethylsiloxane (PDMS) can be used as the sorbent for collecting the pyrolysis products. Further sorbents are possible depending on the configuration.
Automatic sequence
From sample crucible to measurement.
- The PAL RSI removes a crucible with the gripper from the stack.
- He opens the oven lid and places the crucible on the quartz platform.
- The cover closes and locks pneumatically. The PAL software starts the pyrolysis.
- The pyrolysis products pass through the heated transfer line to the sorbent in the OPTIC liner.
- The PAL RTC transfers the liner into the OPTIC injector.
- Thermal desorption and focusing prepare the subsequent chromatographic separation and mass spectrometric detection.

Automated pyrolysis for large samples.
Yassin Hardi introduces the Chromtech pyrolysis oven as an automated solution for large sample volumes. Aluminium oxide crucibles with 600 or 900 µl are integrated into the measurement sequence using PAL sample handling.
The pyrolysis products reach Tenax, SorbStar or PDMS via the heated transfer line. They are then thermally desorbed in the OPTIC-5 and analyzed with GC-MS or GC-MS/MS. The article describes the interaction of the furnace, PAL RSI, PAL RTC and LINEX.
The diagram shows the system overview and automated workflow.
