ECD damage
Posted: Fri Apr 07, 2006 4:42 pm
Greetings!
Our lab has a situation where an analyst was attempting to thermally bakeout a micro-ECD on a 6890. She capped the inlet and with N2 flowing ran the temp up to 330. Unfortunately, overnight the N2 ran out. So the detector was at an elevated temp for a undetermined amount of time. The signal is now at a maximum and after 2 hours of good column and makeup flow at 290C still won't come back down.
Anyone have any ideas as to what we can do next?
Thanks!
