ZEFIRUS TGA-FTIR Interface

ZEFIRUS is the combination of a Thermogravimetric Analyzer (TGA) with an Infrared Spectrometer (TG-IR)

Description

The combination of a Thermogravimetric Analyzer (TGA) with an Infrared Spectrometer (TG-IR) is the most common type of Evolved Gas Analysis (EGA) in use today. Coupling the TGA to a Fourier Transform Infrared (FTIR) spectrometer adds considerable utility to the method.
The vapors released from the material pass through a gas cell inserted in the FTIR, where the spectrum is obtained. Spectral searching provides the last link of vapors identification and thanks to the ability to detect functional groups, FTIR analysis allows greater understanding of the processes seen in the TGA.

Technical specification:
  • Active flow technology: real quantitative analysis with no FTIR signals overlapping;
  • Heated gas cell and SilcoSteel® transferlines up to 350 °C;
  • Zero gravity cell design: no more fouling or dirtiness phenomena;
  • Customized adapter for every TGA model;
  • SRA Kinetic software directly controls Agilent Cary 630 FTIR: time resolution analysis and live quantitative data;
  • Automatic triggering.
TheSRA Kinetic software is a user-friendly software developed to manage real time monitoring analysis for the Agilent Cary 630 FTIR. The acquisition parameters are saved in a single method, and spectra are saved in a single file for post-processing. During the experiment the specialist can display two overlaid spectra and monitors the trend of two spectral areas of interest with the possibility to have a 3D view of spectra over time. SRA Kinetic is compatible with TGA triggered acquisitions and let to have real-time quantification of an interested peak.
