| Criterion | GL Sciences OPTIC-5 Pyro | CHROMTECH Large Volume Pyrolysis |
|---|---|---|
| Pyrolysis principle | Direct pyrolysis in the GC inlet | External furnace pyrolysis with a heated transfer line |
| Method | Py-GCMS – pyrolysis with GC-MS | Furnace pyrolysis with GC-MS |
| Sample amount | Small samples | Larger samples; aluminium oxide crucibles with 600 or 900 µL |
| Temperature | Up to 1,000 °C in the Pyro version | Up to 1,000 °C |
| Heating rate | Up to 100 °C/s | Up to 30 °C/min |
| Automation | PAL RTC with LINEX liner exchange | PAL RSI for up to 80 crucibles; PAL RTC for liner transfer |
| Pyrolysate transfer | Direct transfer into the GC system | Heated transfer line and sorbent collection; followed by thermal desorption in the OPTIC-5 |
| Typical applications | Polymer identification, materials characterisation and microplastics | Thermal extraction/desorption with GC-MS or GC-MS/MS (TED); microplastics in environmental samples and heterogeneous samples |
The appropriate sample mass depends on the material and method. Crucible volume does not specify a fixed sample mass. Temperatures and heating rates are instrument-specific maximum values.

Gas chromatographyLarge Volume Pyrolysis
The large Chromtech pyrolysis oven automates large-volume pyrolysis for microplastics analysis. Large ceramic sample crucibles, PAL RTC, RSI and DHR and a heated transfer line connect sample preparation with GC-MS analysis.
Laboratory automationPAL3 TDAS 2020
Chromtech’s PAL3 TDAS 2020 automates thermal desorption at the RTC PAL. A mobile furnace transfers volatile and less volatile compounds directly from the sample tube into the GC injector – without an additional transfer line.
