GC-ECD Low response
Posted: Thu May 17, 2018 10:54 am
Hi guys, I am just wondering if you all have any idea to why the GC-ECD detector Agilent brand has a much lower response (five times less) response after I did the thermal ECD cleaning ?
Some of the peaks totally disappeared. This is not only on one method but two different methods so I can eliminate out column problem . We changed the liner and septum and trimmed the column too. But the response was still so Low.
We checked the detector part and noticed the detector screw a bit loose so tightened using a wrench . Is that why it have affected the response?
Thank you for the suggestions and I really appreciate it!
