"Measuring hydrogen sulphide concentration in a pH-volatile liquid (such as water or petroleum products) is much more difficult than in a medium like natural gas. This kind of measurement used until now to be confined to the domain of the lab. Your H₂S Analyzer should be able to bring this measurement to online process control and onsite analysis with the same accuracy and performance. This new technology we have followed high interested. We would like to cooperate with your factory in future. ... We would offer your H₂S Analyzer our customers in the United States and other regions worldwide for petrochemistry and waste water treatment."

"Your concept of water and waste water treatment by yourself developed H₂S determination technique is very interesting. This innovative concept of intelligent and demand-oriented H₂S treatment makes it possible to control the dosing of treatment chemicals depending on the contamination of the main parameter hydrogen sulphide. This process protects the environment, saves costs and is an ideal basis for a worldwide solution of odour and corrosion problems caused by H₂S."

"Complex environmental problems require the development and application of new concepts. We think that your concept of H2S separation from aqueous samples and the following direct measurement by a suitable electrochemical sensor is a very interesting approach. This could be a rugged and reproducible analysis system for the parameter H2S as a basis for removal of contaminations in water."
