Regarding new innovations, there continuing improvements to handle low to high H2S requirements, high moisture conditions, fluctuating pressure situations, as well improvements of accuracy to set NDIR & EC analyzers as suitable, very cost effective alternatives to gas chromatographs.

Sensor and analyzer technologies are always evolving. You can expect that performance and operator practicality will continue to improve, and generally with these advancements, costs, especially cost of ownership should also continue to improve.
