Dear Isogeochem,

Our Thermo bellows (reference side, Delta V plus) had a slow leak, about
2.6 mbar/min. I checked the valves around the bellows, and they should be
fine. I was wondering if it is just a sealing problem which could be fixed
easily? or it is a time to replace the whole bellows with a new one? Does
anybody have an instruction to do it? I will appreciate it.

Another question, since we normally don't need the other bellows (sample
side), is it possible to swap them? Is there anything I need to pay
attention when I swap/replace the bellows? Thanks a lot in advance!
