[img]Guys, I´m having troubles with my NPD detector. Suddenly it began to show a message who reads : " SHUTDOWN (# 10) : Back detector fuel gas shutdown"
I´ve already changed the jet just in case, checked the H2 cylinder, changed for a new one, even changed the bead.
When I begin the conditioning of both detectors ( It´s a 6890 GC with uECD and NPD with a bifurcation before both detectors) the uECD shows no issues and the NPD starts to gain temperature and both the air flow set to 60 ml/min and the H2 set to 3 ml/min get to it. When the temperature of the NPD reaches 300 give or take the H2 begins to drop slowly, and show the message above.
Any ideas ????
