I was personally hit by this back in 2015 as a grad student. We called up our process gas supplier and asked for a k-cylinder of Neon and were laughed off the phone, so we ended up running our experiment on krypton for setup and used a lecture bottle of Neon that a partner lab had left over for the few minutes of data collection we needed to get our result[1].

At the time, we were cursing the semi industry for using up all of the remaining Neon with their billion dollar operating budgets...
