Articles in this category Is the maximum temperature of 600°C enough for performing pyrolysis? 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? 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? 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? 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? 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? 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? The OPTIC-4 inlet can go to 600°C and since 2021 there is a special version OPTIC-4 that can reach 700°C. Automation of pyrolysis is done with the CTC PAL systems and can be done for both solid and li... Do I need a cryo-trap? 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? EGA (Evolved Can I do pyrolysis with in-situ thermally assisted derivatization 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 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? Pyrolysis GC/MS analysis is an hyphenated analytical technique which can be applied for insoluble materials such as paint particles, rubbers, polymers, resins, adhesives, … What septa can I use during pyrolysis The top of the OPTIC inlet body doesn't go till the maximum temperature and for that reason a good septa can be used during pyrolysis without problems. Please use: 2406-1018, OPTIC non-stick O-ring Vi...
