On-line sulfur analyzer (H2S) for liquid hydrocarbon
Model SCA-200, SCA-400 DKK-TOA

The analyzer is explosion protected in compliance with TIIS Ex pd IIB T4. The measurement system is based around a high performance semiconductor X-ray sensor Si(PIN) photodiode. This sensor provides a high S/N ratio together with excellent stability. The X-ray sensor has been specially designed for this application and its compact size means that there are no special RI regulations applicable to its operation.

One of the highest design priorities was for the instrument to require reduced and simplified maintenance procedures. This instrument is so stable it can operate correctly for up to one year between calibrations.

The analytical cell features a Beryllium (Be) film window. Traditionally the Be window has been the weakest part if this type of analyzer. However, the improved design of this analytical cell enables the Be window to withstand up to 1MPa pressures and also offer excellent chemical resistance. These features extend the life of the Be window to typically 4 years.
