Hello,

we are using a flame photometric detector for analysis of organophosphoric pesticides. Since we are using the system for 10 years now and the sensitivity should be better, I wonder if it might be neccessary to change the PMT-tube. Is the sensitivity decreasing after several thousand working hours?

Best regards
