| Comments: | CPC3750 is out of action due to what appears to be a blocked nozzle. Inlet pressure to the MFC has dropped to 750. A gradual decline is evident over 3 months, but most notably in the last month. Vacuum appears to have become sufficiently weak inside CPC to prevent butanol from being drawn in. I will inspect the system when possible. I have swapped over to the CPC3772 in the meantime. |
