gas analyzer / carbon dioxide / carbon monoxyde / trace
EGA
Vnation JSC

-
Measured entity:
gas, carbon dioxide, carbon monoxyde
-
Measured value:
trace
-
Other characteristics:
in-situ, real-time, FT-IR, laser
-
Technology:
UV fluorescence
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 instrument
