Evolved Gas Analysis - FTIR (EGA)

The combination of a Linseis Thermal Analyzer with a FTIR is especially interesting in fields such as polymers, chemical and pharmaceutical industry. The coupling is more than the sum of the separate parts. Benefits come from the LINSEIS coupling knowledge and integrated hard- and software concept. For interpretation different libraries are available.

Possible Couplings:

Thermobalance + FTIR Spectrometer in the temperature range from -170°C up to 1750°C

• L81/I-FTIR Thermo balance + FTIR Spectrometer
• L81/II-FTIR Thermo balance + FTIR Spectrometer
• STA PT 1600-FTIR Thermo balance + FTIR Spectrometer
• STA PT 1000-FTIR Thermo balance + FTIR Spectrometer

Thermo balance with coupling to JASCO FTIR spectrometer. The coupling is made with a heated capillary.

Features

• Research balance (different models) with TG or simultaneous TG/DSC or TG/DTA measurement.
• High precision JASCO FTIR spectrometer (different model available).
• Temperature range -170°C up to + 1750°C Three separate heating zones, at capillary, at TG protection tube and at FTIR measuring cell.
• Carrier gas with wide range of flow rates. Especially developed JLF-detector with long optical pass length.

Description

Both manufacturers Linseis and JASCO are some of the leading companies in their specialized fields. This cooperation guarantees outstanding performance for the combined system.

• Transfer line is temperature controlled up to a maximum of 250°C.
• Fast response time through short transfer line.
• FTIR detector with very high sensitivity and with different wave numbers available.

The following applications can be measured: Outgasing components of burned material (paints etc.) Determination of blenders and additives. Absorption and Desorption processes. Analysis of rubbers and plastics.

Pulse-Analysis

The Pulse-Analysis injects a exactly predetermined amount of liquid or gas into the Thermobalance (TGA) or Simultaneous Thermal Analyzer (STA). This enhances the measurement possibilities significantly: the MS or FTIR can now be calibrated. Out gassings can be quantified precisely with this method.
