      > pressure sensor price quotation: minimum order 5pcs (750EUR), 7-8 weeks lead time 
      > MFM ordered, they will let us know the lead time: 5 weeks on price quotation but to be confirmed
      > M2 exhaust into compressor/storage not worth the effort, few liters of CF4 in low %
         (difficult to separate in a second phase), https://eloggas.web.cern.ch/RICH2+Recuperation/79
      > system exhaust into compressor could be worth, concentration will be 90% CF4 and membranes are efficient
         accumulate gas into battery during run, when full send to membrane? can be separated from system and used by itself? if done during run, purifier will not be available for last purification stage (CO2 2%-> 0.2%)
      > gas from purifier regeneration may not be the good quality, it could be sent to compressor as well? 
         if it is sent together with the exhaust gas could compromise quality > compare quantity 
         even if storage gas (exh+purif) is not optimal quality it could be purified quite efficiently with membrane
