      questions for meeting with KNF:

      -pump purif (going out of production and what about spare). to send more info to KNF to check if there are other alternatives

      -analysis pump production will continue? for how long?

      -O2 intake from analysis pump 10-3 -> 10-5 and now 10-4 other pump models for low flow? 

      -do we want the broken pump back?

      DAMIANO:

      • C4F10 RRS necessity to dismount the extraction pump and repair it. Discuss possibility to test th eKNF N922 ST model. Add a pneumatic valve between XMFC10260 and extraction pump. Add a valve between top buffer e zimmerli.
      • R134a Distillation I only see Fabio available but also Abdel is needed for welding volumes/buffers/column (at least one full week). If we do not proritize this part me and Fabio will have to stop at a certain point. So it would be better to have them in parrallel or Abdel first.
