Service & reparation Request a quotePossible 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 non polar molecules like H2 or N2 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 a 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 instrument
