Innov Dualsulf - Model 400 Series - Gas Analyser Brochure

The metered sample is mixed with a continuous flowing stream of hydrogen. The mixed gases are heated together in a reducing catalytic furnace at a temperature between 650°C and 1200°C, depending on application, where the sulphur compounds in the sample are converted to H₂S. Using the NOVASULF™ series colorimetric analyser, the resulting H₂S is measured on channel one and in parallel the H₂S is measured on channel two. Temperature (zero) drift is eliminated in this analyser by the use of a single optical sensor.
