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

 

The Thermal conductivity Analyzer module is usually provided in a Continuous Emissions Monitoring System (CEMS) or in a Process Analysis integrated solution.

 

According to the application intended you can choose between the following analysis modules:

 

CALDOS25 – for highly corrosive applications;

CALDOS27 – for the smallest measurement ranges and fast measurements.

 

MEASURING PRINCIPLE:

 

Differences in the thermal conductivity between gases.

 

COMMON APPLICATIONS - CALDOS 25:

 

• Chlorine production;
• Analysis of SO2 in metal roasting plant off-gas;
• Ammonia Dissociation.

 

COMMON APPLICATIONS - CALDOS 27:

 

• Hydrogen Purity measurement;
• Turbo generator monitoring;
• Inert gas monitoring;
• LEL (Low Explosive Limit) monitoring.

 

EXAMPLES OF THE COMPONENTS AND THEIR RESPECTIVE SMALLEST MEASUREMENT RANGE - CALDOS25:

 

• H2 in N2 or Air 0…0,5% Vol;
• SO2 in N2 or Air 0…1,5% Vol;
• H2 in CL2 0…0,5% Vol.

 

EXAMPLES OF THE COMPONENTS AND THEIR RESPECTIVE SMALLEST MEASUREMENT RANGE - CALDOS27:

 

• Air in O2 0…2 Vol-%;
• H2 in Air 0…0,25 Vol-%;
• H2 in N22 0…0,3 Vol-%;
• CH4 in N2 0…2 Vol-%;
• Air in N2 97,5…100 Vol-%;
• He in N2 97…100 Vol-%.

 

CALIBRATION:

 

Automatic calibration by means of internal control;

Zero-point calibration with sample component free process gas or substitute gas;

End-point calibration with process gas having a known sample gas concentration or with substitute gas;

Simplified calibration with standard gas avoids the need for separate Zero-point and End-point calibration with test gases.
