This technology allows multiple analysis on a single sample. There is no need for solvent and sample
preparation as the sample is simply introduced into the GCMS by the Frontier Pyrolyzer.
Auto-Shot Sampler: A 48 position auto sampler compatible with both the single and multi shot pyrolyzers used for pyrolysis, TD or EGA
Multi-Mode Pyrolyzer: Vertical Micro-Furnace technology with low heat capacity ceramic heater that enhances more rapid heating and cooling rate. Pyrolysis temperature ranging from room temperature up to 1050°C.
Selective Sampler: Any set of EGA thermal zones can be heart-cut and the components introduced into a capillary column or vented
MicroJet Cryo-Trap: Cryo-traps low boiling compounds at the front of capillary column by cooling a spot of the column to -196°C using Liq. N2. The universal design allows it to work with most sample introduction devices.
Ultra Alloy Metal Capillary Column: Ultra ALLOY® columns are available with a number of stationary phases including polydimethylsiloxane and polyphenyl-methylsiloxane. The Frontier stationary phase polymers bonded to the Ultra ALLOY® surface resist oxidation at elevated temperatures and can be rinsed with a number of common organic solvents.
Vent-Free GC/MS Adapter: Allows switching a separation column and EGA tube without venting the MS system.
F-Search: The system consists of F-Search software and four types of libraries listed below. The F-Search system allows you to rapidly search the libraries for polymers and additives. In the latest Ver. 3.6, the number of polymers stored in all three polymer libraries has been greatly increased.
Pyrolysis GCMS is a powerful and simple technique comprised of a Frontier Pyrolyzer coupled with a gas chromatography mass spectrometer system. Using this technique, sufficient amount of heat is used to break down the organic bonds of a complex specie into smaller and stable molecules referred to as pyrolyzates. The pyrolyzates formed and their relative intensities provide insight into the nature of the original material.
This technique has a wide variety of applications for identifying organic composition of unknown samples by providing detail information about the compounds present in a sample. Such as compounds’ molecular formula, structure, and eluting time.
Pyrolysis GCMS is used for identification of complex polymers, copolymers, volatiles, and additives. This technique which can be used both qualitatively and quantitatively, allows multiple and customized analysis on the same sample.
Polymeric materials often contain a variety of additives, such as antioxidants, UV absorbers, etc. To assist during the production phase and determine the physical and chemical characteristics of the final product. These compounds are identified using commercial mass spectral (MS) libraries; however, these general-purpose MS libraries contain very few entries for pyrolyzates and additives which severely limits their utility for polymer characterization.
Frontier Laboratories developed a search engine and libraries called F Search. The ions associated with hundreds of polymers, their degradation products (i.e., pyrolyzates) and hundred of additives are used to identify and thus characterize the sample as it is heated in the Py.
The libraries include both chromatographic and mass spectral data. There are four unique libraries which allow users to select among them for specific purposes. The ability to create in-house specialty libraries is incorporated into the standard software. Updating these libraries is straightforward.
