Sulfur compounds included in fuel and lubricating oil have a negative influence on life time of post-processing system to purify exhaust gas (sulfur poisoning phenomenon). In order to improve that, we have to strictly make clear reaction mechanism. That's why, accurate measurement is very important.
In addition, we need to decrease H₂S generated during catalysis reaction, as stimulus smell. CRDS doesn't need any specific chemicals and can measure the only H₂S with stability.

●CRDS=Dry measurement
　CRDS doesn't need any specific chemicals
　and is safe measurement.
　High speed response and high accuracy.
●High selectivity by CRDS and S-FPD
　Fine cross interference of other gases.
●High sensitivity and wide range
　H2S 0-5〜500 ppm
