Has anyone run into problems with a small baseline pulse in a conductivity detector? I'm running a Dionex 2000i Cation Chromatograph and am seeing a baseline pulse of about 0.8 MicroSeimens.

I've tried cleaning the detector with 1N HCl and water, setting the temperature compensation to 0, and even switching in a new detector. Nothing seems to work.  I also know it isn't a power supply problem because I am running anions in series and that detector remains stable.

Any suggestions would be appreciated! Thanks!

If any of the 96 chemists that read this post are interested, we have solved this problem. It was a combination of faulty check valves and pressure transducer. :-)
