Chemstation B.04.03 not recording both FID channels, HELP..
Posted: Mon Aug 31, 2020 5:23 pm
Just switched over to B.04.03 version, running Headspace with Dual FID on 5890 Series II.
I use front injector
I have a Y at the inlet and have two columns, one going to FID A and the other to FID B
On the method I select SIG A and SIG B, front injector
In pre run, I can monitor both Detector signals, but once the run starts, for some reason, the computer output is the same (Det A) for both Sig A and Sig B. I can not see the other signal.
I am wondering if I am missing something. If any of you have the same system please advise.
Thanks in advance for any help.
