##June 2012## In the United States The National Helium Reserve supply chain is currently disrupted. The price has spiked and some supplies are not selling to non-commercial users. We have been asking our suppliers and they expect the situation to improve before the end of the year.

One notable aspect being considered is giving Scintists priority in the event of a shortage. http://www.physicstoday.org/daily_edition/politics_and_policy/senate_bill_would_preserve_us_helium_reserve http://old.post-gazette.com/pg/10354/1111632-115.stm ##Re-Capturing Helium## Problem: re-capturing helium in a pressurized tank without contaminating it for reuse.
