Today, most laboratories are integrating the Frontier Multi-Shot Pyrolyzer into their mainstream analytical protocols due to the advantages and immediate quality improvements this technique provides. In addition to the reliability, accuracy, precision, automation, and reproducibility of this technique, Pyrolysis GCMS has several advantages over a regular GCMS system.
As we all know, a GCMS system can be used only for material characterization of liquid or gas samples while the maximum GC inlet temperature is around 320°C. In addition, a GCMS system is limited to organics that vaporize at < 320°C. Only single analysis per sample can be performed with this technique. On the other hand, Pyrolysis GCMS technique which is comprised of a Frontier Multi-Shot Pyrolyzer coupled with a GCMS system, enhances the capabilities of a GCMS instrumentation.
Using Pyrolysis GCMS, solid samples can be analyzed in addition to liquids and gases. In fact, there is no solvent required when using Pyrolysis GCMS as opposed to GCMS technique. In other words, the solid and liquid samples can be injected into the Pyrolyzer without any solvent and sample pretreatment like solvent extraction! This advantage is one of the primary reasons for many laboratories to integrate the Frontier Pyrolyzer into their day to day and research analytical protocols. Think about the amount of money laboratories with this capability can save over time. In addition to eliminating solvent costs, these laboratories are protecting their scientists from solvent exposure while operating environmentally friendly.
Pyrolysis GCMS technique also enables material characterization of virtually any organics by providing detail information about the composition of the samples. This technique is used for identification of complex polymers, copolymers, volatiles, and additives as well as failure, contamination, deformulation, and degradation analyses. As opposed to GCMS, Pyrolysis GCMS allows multiple and customized analysis on the same sample while the MS libraries offer a broad range of references: from low b.p. compounds to pyrolyzates and heavier polymeric fragmentations.
In terms of the ability to run samples at higher temperature, the Frontier Multi-Shot Pyrolyzer provides the user with an expanded temperature range from ambient + 10 to 1050°C ± 0.1°C precision as well as a high Interface temperature of maximum 450°C.
Frontier Multi-Shot Pyrolyzer allows multiple analysis on a same sample. One of these analyses is Evolved Gas Analysis (EGA) which provides the user with a clear picture of the unknowns’ composition by identifying the thermal zones and the compounds in each zone. In other words, EGA thermogram of a sample determines the accurate temperature (s) zones for identifying the composition present in the sample. In fact, sufficient amount of heat is programmed via the Pyrolyzer to obtain the information of interest about a sample. Therefore, there is NO overheating and/or underheating on the sample!
