SCD 355 loosing sensitivity over time

Hi - we have an old SCD 355 coupled to a GC×GC instrument running sulfur speciation in petroleum samples.

Over the last 5 years the sensitivity of the detector has decreased significantly, which in practice is seen as elevated background noise and thus a lower limit of detection.

We have considered changing the reaction cell to regain the sensitivity - any experience on the effect of such a replacement?

Looking forward to receiving your expert inputs :-) BR Karina
