8355 SCD high output

I operate an Agilent 8355 SCD. The  baseline output that is stated in the manual is 150pA in a well stabilized system with an oven temperature of 50C. When not in use, the baseline output is around 500pA. I'm not sure if this is caused by the method I use/frequency of use or if there is an issue with the detector itself that needs to be addressed. Any thoughts on the cause of a high baseline output?

  • update on the situation. Agilent service came today and basically rebuilt the reaction cell. The instrument will pump down/equilibrate overnight and will run a sample in the morning to see if the issue is fixed. The service guy will be back in the morning to check the instrument again.
