ECD signal suspending (hanging on) Perkin Elmer AutosystemXl
Posted: Mon Mar 06, 2006 7:18 am
Hello
I decided to post in this forum because I have no idea what to do.
Signal of my ECD is suspend (stay constantat highest value) when high concentration reach the detector (high peak). Value of signal increase to about 620 mV and don’t drop down even 12 hours. But when I plug outline from ECD for few second then signal drop down to normal base line.
Detector was baked, anode was cleaned and situation is still the same. Base signal of detector without column installed caped with a pulg, (temp 350, Nitrogen 30 ml/min) is about 2,5 mV.
Have you got any suggestions what is wrong?
