Analytical scientists and manufacturers working on new product development and process improvements need the ability to perform in-depth characterization of materials to obtain a more complete picture. A single analytical technique provides useful information, but it’s often not enough to gather the depth of insights necessary to completely identify and characterize complex mixtures, analyze evolved gases or evaluate competitors’ products. Missing these insights contributes to the loss of precious time, productivity, and revenue, resulting in sub-optimal products and processes.
To achieve more complete, in-depth characterization, coupling or the hyphenation of two or more instruments is required to enhance and complement the quality of information and to gain a more complete picture of the materials. These deeper insights lead to better product performance, reduced costs, and improved recyclability. Hyphenation reveals new information and insights that will provide your laboratory with a competitive advantage that is simply not available with single system analyses.

Value of EGA Hyphenation EGA Hyphenation combines a TGA instrument with one or more additional detector technologies, such as FT-IR, MS and/or GC/MS; the most powerful being TG-IR-GC/MS. TGA measures sample decomposition of materials (weight loss event) which provides valuable but limited information. TGA provides quantitative information but does not provide information on what the decomposition products are concurrent to the weight loss. The power of EGA Hyphenation is its ability to carry out in-depth characterization of the "evolved" gases. |
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:

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.

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.

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.

All PerkinElmer EGA Hyphenation systems include the master digital controller and pump, that ensures balanced flow while controlling temperature, flow, and pressure. The controller includes temperature controlling devices, mass flow controller (MFC), flow smoothing system, filters and pump with exhaust line.
