Hyphenated Technology

Hyphenated System: TG-IR/TG-MS/TG-GC-MS/TG-IR-GC-MS

Features:

TG-IR: Thermogravimetric – Infrared Analysis
Because of its ability to detect functional groups in gas-phase, IR analysis allows greater understanding of the processes seen in the TGA. A sample is heated in the TGA, whereby, it decomposes and releases volatile materials and/or gaseous components as a result of material break-down. These gases Thermogravimetric properties are recorded and are then transferred to the IR cell via a high-fidelity transfer system where the components can be further characterized/identified.

TG-MS: Thermogravimetric – Mass Spectrometry Hyphenated Analysis
The ability to detect very low levels of impurities in real time makes TG-MS a powerful tool for quality control, safety, and product development. Samples heated in the TGA release volatile materials and/or generate gaseous components that are seamlessly transferred via a high-fidelity transfer system to the MS for identification.

TG-GC/MS: Thermogravimetric – Gas Chromatography/Mass Spectrometry
The ability to detect very low levels of material (known and unknown) in complex mixtures makes the TG-GC/MS a powerful tool for quality control, safety, and product development. Heating a sample on the TGA causes a sample to release volatile materials and/or generate gaseous components upon decomposition. These gases are then transferred via a high-fidelity heated transfer system to the GC, where the components can be collected on a trapping media, in a gas sampling loop, or deposited on the head of a column. The sample can then be run by GC to separate the material, and the peaks identified by the MS.

TG-IR-GC/MS: Thermogravimetric – Infrared – Gas Chromatography/Mass Spectrometry
Hyphenating TG-IR-GC/MS is a powerful approach for analysis of an unknown mixture to determine its primary components and identify additives or contaminants. This information may be needed to evaluate a competitor’s product, determine compliance with regulations, or understand a material’s composition. The PerkinElmer TG-IR-GC/MS high-fidelity heated transfer system enables TG-IR-GC/MS analysis on a sample by moving every component in the off gases to the FT-IR and/or GC/MS after their evolution in the TGA while maintaining complete sample integrity.
