Application Note

Rapid Response Time At four measurements per second, the analyzer can measure the fastest changes in the pipeline. Adjustable, real-time results display every 0.25-2 seconds.

No Consumables Because the analyzer’s sensor head never touches the gas stream it does not get contaminated. The factory set calibration lasts for the life of the analyzer and reconditioning is never required.

Payback

The SS500 very quickly pays for itself by doing away with expensive consumables, extra sensor heads, labor and overhead associated with excessive maintenance. Costs due to unreliable gas measurements can be reduced by eliminating added processing steps, poor gas quality and the possibility of damage to expensive equipment can result from sensors that produce incorrect data.

No Interference As with all SpectraSensors analyzers, the SS500 combines a patented laser with control electronics and “smart” software. The analyzer’s sensor heads are not subjected to corrosives or contaminants in the gas because the sensor is isolated from the sample gas stream.

The result is an analyzer which does not suffer from contamination or drift due to vapor impurities such as glycol, methanol, amines, hydrogen sulfide, or mercaptans.

State of the Art Technology The analyzer works by shining a laser beam through the sample cell. The laser beam is selected to interact only with the measured compound, creating an absorption signal. The higher the concentration of H2O the greater absorption of light and the stronger the corresponding absorption signal. Spectrum Software analyzes these absorption peaks to produce very accurate and repeatable measurements. Since the calculation is a direct, fundamental measurement, the amount of H2O present can be measured in realtime.
