TG-IR

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

For additional information, please refer to the Evolved Gas Analysis Guide below.

TG-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

For additional information, please refer to the Evolved Gas Analysis Guide below.

TG-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

For additional information, please refer to the Evolved Gas Analysis Guide below.

TG-IR-GC/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.
