We are in Denver, and we are using Linde (merged with the BOC gases - which we used before that) for liquid helium for 10 years. No contract ever signed.
For liquid nitrogen we use Airgas - and yes, we have to use them only, signed institutional contract with the University of Colorado (so, I have no choice).

Subject: RE: helium shortage and allocation contract agreement.
We use a local company, Airgas for our cryogen (liquid helium, liquid argon and liquid nitrogen)needs. So far, we have not had to sign an allocation agreement. However, the supply is definitely tight, and supplies are hard to get.

Subject: helium shortage and allocation contract agreement.
Dear colleagues,
Because of the helium shortage, our cryogen supplier Praxair recently encouraged us to sign an allocation agreement with them. Basically, we are to only purchase liquid helium from them for the next year or two and we will probably receive less helium and experience delays. Our lawyers have looked into this and discouraged us to sign the form. I was wondering if your institution has signed an allocation agreement with your cryogen supplier or decide to "ride the storm."
Please advise.
