IME SA provides a wide range of gas analyzers using different analysis modules according to the characteristics of the sample and the application intended.

 

The Ultraviolet Gas Analyzer allows an analysis of 1 up to 5 measurement ranges per sample component with the possibility to freely adjust the ranges within a ratio of 1:20.

 

It incorporates electronic zero-point suppression within a maximum suppression ratio of 1:10.

 

MEASURING PRINCIPLE:

 

Gas filter correlation or wavelength comparison in ultraviolet and visible spectrum range ʎ = 200 to 600 nm.

 

COMMON APPLICATIONS:

 

• Burner Optimization;
• Control of DeNOx Installations;
• Emissions monitoring of FCC Furnaces;
• Nitric Acid Production;
• Purity Measurement in the Chemical Industry;
• Production and Processing of Cellulose and Viscose;
• Natural Gas Treatment;
• Chlorine Production and Processing;
• Plastic Production.

 

EXAMPLES OF SAMPLE COMPONENTS AND THEIR RESPECTIVE SMALLEST MEASUREMENT RANGE:

 

• NO 0…10 ppm;
• SO2 0…25 ppm;
• NO2 0…50 ppm;
• H2S 0…25 ppm;
• CL2 0…125 ppm;
• CS2 0…50 ppm;
• COS 0…250 ppm.

 

CALIBRATION:

 

Zero-point and end-point calibration with gas filled calibration cells or test gas mixture;

Automatic calibration by means of internal control.
