I work with an HPLC 1260 AGILENT and I have some question about the detector DAD
1 : during the analyse the DAD was an error (red light) and if i go to the lab advisor and test intensity the error message is "lamp overcurrent", i don't understand because we pass 8 injections and we have no problem during analysing...The lamp was changed on january 2017.....and we pass 2500 analyzes maximum.....
2: for the intensity test for DAD, we need to pass water is it correct ?
3: about chemstation (software with our hplc) if i go on set up instrument method i don't see the timetable with our method but graph ...is it possible to return withe the timetable ? if yes what is the procedure ?
thank's a lot for your answer
