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?

  • The SCD is fixed. The reaction cell was replaced and the tech adjusted the oxidizer/hydrogen flow ratio. The oxidizer flow was lower than the hydrogen flow which can cause problems over time. The output is currently fluctuating between 50 and 60 pA while sitting.
