TGA-FTIR
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.
A few advantages of this system include:
- State-of-the-art – ensure transfer of every component evolved in the TGA to the IR while maintaining complete sample integrity
- Performance – Heated zero-gravity-effect ‘ZGCell’ gas cell for the PerkinElmer FT-IR instrument incorporating automatic accessory identification, low volume, and efficient sample area purging
- Flexibility – Switch from TG-IR mode to TGA and/or IR only mode quickly and easily
The needs for polymer, pharmaceutical, chemicals, food and beverage, and environmental analyses are constantly changing due to innovation demands and regulation changes.
Evolved Gas Analysis (EGA) solutions combine multiple analytical technologies to empower speed and advanced information acquisition. Coupling Thermogravimetric Analyzer (TGA) systems with other analytical systems such as Gas Chromatography Mass Spectrometry (GC/MS) and Fourier Transform Infrared (FT-IR) Spectroscopy represents the most complete and advanced EGA solutions for gaining insights beyond decomposition of materials, by carrying out in-depth characterization of the evolved gases.
TGA-MS
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.
A few advantages of this system include:
- State-of-the-art -The TG-MS is equipped with a transfer line with adjustable heating capabilities up to 350 °C, a mass flow control, and pumps
- Performance – TG-MS enables high sensitivity measurements in real time
- Flexibility – Switch from TG-MS mode to TGA and/or MS only mode quickly and easily
TGA-GC/MS
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.
A few advantages of this system include:
- FAST GC capable with the Clarus 690, benefits of FAST GC include:
- Faster results with time savings up to 80%
- Analyze multiple events in a single run
- Double event separation
- Automatic triggering by time or weight loss
- Better than Pyrolysis
- See the decomposition and choose when to start sampling
- Choose to analyze individual losses to identify what they are
- Analyze the total weight loss to quantify the percentage of that component in the sample
- Better Separations & Detection of lower-level impurities than TG-MS
- Flexibility –switch from GC separation (TG-GC/MS mode) to Single Ion Monitoring (TG-MS mode) to TGA and/or GC/MS only mode quickly and easily
TGA-IR-CG/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.
A few advantages of this system include:
- Performance – Maintains the relationship between the temperature each gas is released at and its corresponding components through FT-IR
- Sensitivity – The sequentially measuring of the off-gas components by GC/MS enables detection of trace levels too low to be seen in the FT-IR
- FAST GC capable with the Clarus 690, benefits of FAST GC include:
- Faster results with time savings up to 80%
- Analyze multiple events in a single run
- Double event separation
- Automatic triggering by time or weight loss
- Flexibility – Switch from TG-IR-GC/MS mode to TGA, IR, GC/MS and/or GC mode quickly and easily For additional information, please refer to the Evolved Gas Analysis Guide below.
