IME SA provides a wide range of Laser Spectrometers for the chemical and petrochemical industries, refineries and for Natural Gas and Process applications.

 

The Single Channel Laser Spectrometer was especially developed for Natural Gas Applications, being able to measure H2O and CO2.

 

The sensor measures gas using a patented Tunable Diode Laser (TDL) to determine the concentration of the gas without coming in physical contact with the stream. Therefore, this analyser allies optimal precision and quick measurement to low operational and maintenance costs.

 

MEASURING PRINCIPLE:

 

• Tunable Diode Laser Absorption Spectroscopy.

 

KEY FEATURES:

 

• Rapid Response Time – takes four measurements per second with a lser and a detector and immediately averages the results. Because there is no contact with the gas, real-time measurements are not hampered by wet-up or dry-down as with surface based sensors;
• Long Life – The TDL sensor does not enter into contact with the sample gas stream. The result is a sensor that does not suffer from contamination or drift due to vapour impurities such as glycol, methanol or amines;
• Ideal for Harsh Environments – The enclosure can be provided in Cast Aluminium or Stainless Steel 304;
• Low Maintenance Costs – requiring no consumables.

 

COMPONENTS AND MEASURING RANGE:

 

• CO2 in Natural Gas: 0-5%, 0-10%, 0-20%;
• H2O in Natural Gas: 0–422 ppmv, 0-1.055 ppmv, 0–2.110 ppm v.
