Is the maximum temperature of 600°C enough for performing pyrolysis? Article rated 3.0/5.0
yes, most (co-)polymers degraded by temperatures lower than 600 °C. When you check pyrolysis publications you will find that most of them stay below 600°C. You can find 
Is the ramp rate of 60°C/sec fast enough to perform pyrolysis? Article rated 3.0/5.0
For pyrolysis high temperatures are needed, for good peak shapes a  fast ramp rate is needed. A ramp rate of 60°C/sec will give nice peak shapes  that easily can be detected by GC/MS. &...
Is it possible to introduce a liquid sample? Article rated 3.0/5.0
Yes that is possible, it is even recommended. When the polymer solution is injected into the PTV-pyrolyser, the results can be quantitative. Even Large Volume Injection Pyrolysis can be done. For liq...
Can I introduce a solid sample? Article rated 3.0/5.0
Solid samples can be introduced into the OPTIC. It can be done manually and automatically by the LINEX system. The sample can be placed in the fritted liner or one of the available micro vials.  ...
Will my column be damaged because it is in the pyrolysis chamber? Article rated 3.0/5.0
The top of the column is indeed installed inside the chamber which is heated normally above the maximum temperature limit of the GC-column, however, this is not a problem. When the column is installed...
Do I need quartz liners? Article rated 3.0/5.0
No, normal glass liners can be used until 600°C but it is better to use the liner for a short time on this temperature. (about 10 minutes). When it is needed to use a liner for a longer time at h...
Why should I buy an OPTIC pyrolyzer and not a conventional pyrolyser? Article rated 3.0/5.0
With the OPTIC automation of pyrolysis is very simple.  Only with the OPTIC and liquid injections, quantitative pyrolysis is possible. The whole set-up is simple and no modification to your GC is...
Do I need a cryo-trap? Article rated 3.0/5.0
A cryo-trap will improve the peak shapes and gives you better chromatograms, but is not always needed. 
Is it possible to make an EGA thermogram with OPTIC? Article rated 3.0/5.0
EGA (Evolved
Can I do pyrolysis with in-situ thermally assisted derivatization Article rated 3.0/5.0
Pyrolysis GC MS is widely used technique in the structural analysis of polymeric materials. A major disadvantage of these techniques is their limited applicability for the ch
Dirty liner in the top Article rated 3.4/5.0
A dirty liner with dirt in the top of the liner on the outside after many samples is normal. A liner t
Is is possible to make a Double Shot Pyrolysis with OPTIC? Article rated 5.0/5.0
Pyrolysis GC/MS analysis is an hyphenated analytical technique which can be applied for insoluble materials such as paint particles, rubbers, polymers, resins, adhesives, …
