baseline problem with Hewlett-Packard 5890

I am a new user of this instrument. I got strange baseline when I set oven temprature at 200 C. The baseline rapidly rise to saturation of detector start from low level . I tried adjust the attenuation but the ECD detector did not response. Then I tried reduce oven teperature to 20 C, baseline still the same. What the problem cuold be? Or something wrong with setting?

My guess would be that you

My guess would be that you have an air leak at the connection at the detector side of things. If its at all loose, air will leak in and peg your ECD.
