Bellows just gets bad after certain number of samples (about one to two years) and starts to leak. You just need to change a new one. We changed twice in less than 4 years.You cannot swamp with another one, as you need two side bellows later for hardware and signals calibration.

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!
