Hi Carlos,

We have two systems equipped with GaAsP detectors and one with HyD and I can tell you that these detectors do age.
We averagely need to exchange the GaAsP every 2500-3000 hours. Which means approximately once every 18 months for us.
Regarding the HyDs, we have a very new system equipped with them. So I cannot tell much, but we already experienced some hot pixel and comet problem.
In fact one of the detectors has already been exchanged.

With this I don't want to say that they are bad or inconvenient.
Quite the opposite! They truly do a much better job than PMTs. If I could, I would always go for these more sensitive detector.
But one must keep in mind that they are consumables.

I hope this helps.

Best,

D.
