AMMRL: oil contanimation in cold probe helium lines

Hello,

We unfortunately have got some oil into the flex lines and CCC that supply
helium to one of our cold probe. It looks as though a small amount of oil
got into the system before the adsorber was last changed, and is migrating
through. I'm told that the oil has not made it past the molecular sieves
in the CCC, so the probe is fine.

Does anyone have some recommendations regarding who/how to clean this out?
Our 500 with cold probe has been a great workhouse, but without the cold
probe it isn't as useful for some users, so I'd love to get it back into
working order as quickly and affordably as possible.

Thanks very much,

Tara
