EGA-Optical In-Situ

In-Situ EGA - Coupling

Description

To the point

Possible Techniques:

  • FTIR: Fourier Transform Infrared Spectroscopy: Measurement of basic and trace gas components until ppm range (for example H2O, CO2, CO, H2S…). Polar Molecules are necessary.
  • Raman-Spectroscopy: Measurement of basic gas components. Also not polar molecules like H2 or N2 are measurable.
  • ELIF: Excimer Laser induced Fragmentation Fluorescence: UV-Laser-based Method of Measuring of gaseous alkaline compounds (for example NaCI, NaOH, KCI, KOH). Also at 193 nm an entry through UV_Saphire is possible.
 

Advantages of the optical In-Situ window:

  • No Cooling / Modification of the measuring gas (for example no out-condensation, no transition reaction, no equilibrium shift)
  • Many materials with high condensation temperature for example alkali metals (Na, K and their combinations) are now able to be measured, heated capillary only suitable for some 200 – 250°C, the optical port allows measurement until 1600°C
  • No intervention into the measuring system (for example when pulling gas by vacuum)
  • No contamination of the measuring gas in the capillary to M/S or FTIR
  • Real-time online-Measurement (no dead time until measuring volume enters the measuring instrumentIn-situ_measurement

Unique Features

No cooling required:
Avoids changes in the sample
gas and enables more precise
measurements.

High temperature measurements:
Measurements up to 1600°C,
ideal for materials with high
condensation temperature.

No interaction with the measuring system:
Prevents contamination and changes in the
sample gas.

Real-time online measurement:
Immediate results without waiting times.

Multi-faceted
measurement methods:

use of FTIR, Raman
spectroscopy and ELIF.
