We run a bunch of agilent uECD and one in particular is acting up. It is giving a signal that oscillates up and down quickly, when zoomed in and doing the math it's about 4.8hz frequency. Looks like electronic spikes with sharp points. When viewing the whole chromatogram the baseline just looks like a fat black line.
I suspect it's something in the detector and not flow. I don't think flow fluctuations would present itself with such sharp peaks so quickly. Trying to find an answer online and hitting a wall. Any suggestions would be helpful. Thank you.
