Hello everybody, we use (master 1000 DANI) GC for analyse. I have problem with solenoid valve (brand: SIRAI V366B01BL). I hear leaking at the solenoid valve, when i inject sample to the GC after a few minute air leak will stop and we hear no sounds but after finish the run time leak start again. now i dont know how to fix it?
