Thermogravimetric analysis (TGA) measures the change in sample weight as a function of temperature or time in a controlled atmosphere. This weight change is usually accompanied by an evolution of gases caused by sample decomposition or volatilization. TGA-IR Interface for Nicolet FT-IR spectrometers identifies the components of evolved gases that determine sample characteristics, which cannot be identified using TGA analysis alone.
Product Detail
The TGA-IR Interface for Nicolet FT-IR series spectrometers combines the sample analysis tools of a TGA with the identification power of an FT-IR spectrometer.
The TGA-IR Interface and OMNIC Series software combines Nicolet FT-IR spectroscopy with TGA to offer real-time monitoring of gases as they evolve from a sample. The combined system measures the change in weight of a sample as function of temperature or time in a controlled atmosphere and collects IR spectra of the evolved gas components.
The TGA Interface is connected to the TGA via a heated transfer line. As gases evolve during the TGA experiment, they pass into the flow cell of the TGA-IR interface where the infrared spectra are collected. The TGA-IR Interface is beneficial in determining sample characteristics such as decomposition pathways, thermal stability or sample integrity. Its flexible interface design can be placed in the sample compartment of the Nicolet FT-IR spectrometer or in an Auxiliary Experiment Module (AEM) of a Nicolet iZ10 module. The TGA flow cell is compatible will all types of evolved gases and materials. Additionally, the large flow cell diameter provides high throughput and prevents spectral interference caused by deposits on the walls. The TGA-IR Interface features a flow cell that is spring loaded and easily removed for cleaning.
