Innov Analytical Systems (IAS) products

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.

Duty: To measure the concentration of H2S in a process gas stream. The principle of operation is as follows. A reel of paper tape impregnated with lead acetate is exposed to the gaseous process sample in the sample chamber. Hydrogen sulphide (H2S) in the process sample reacts with the lead acetate, after acidification, to form lead sulphide (PbS), a brown compound that stains the tape.

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 NOVASULFTM TG series colorimetric analyser, the resulting H2S is measured. Temperature (zero) drift is eliminated in this analyser by the use of a single optical sensor. 

The WATERSULF Series analyser is dedicated to the measurement of dissolved sulphides in water up to pH 8.5.

The measurement principle is based on a variation of HENRY`s law: the weight of any gas dissolved in a definite volume of liquid is directly proportional to the partial pressure the gas exerts above the liquid at a constant temperature. The Analyser consists of a stripping system coupled with an H2S Analyser NOVASULFTM HG SERIES.

Principle: Chemical reduction colorimetric detection. Rangeability: 0-250 PPB up to 0-5000PPM. Monitoring: By a PC via a propriarity Software. Installation: Laboratory bench, safe area.

Principle: Diphosphorous, pentoxyde (P2O5) sensor, dissociation of water.
