Task of the day: trying to order a new canister of compressed gas to replace the one that the group last ordered…6 years ago. Apparently in that time span the friendly local gas company the group used to use got bought out by Bigger Badder Gas Company (see, it doesn’t just happen to grocery stores), so they had no idea what we needed.
It also didn’t help that the gas was a little non-standard. Argon or nitrogen or something would have been easy enough to order whether we had the product number or not. Forming gas made from a 5% mixture of hydrogen in nitrogen? Not so much. They had a 10% mixture instead, which would have been great if we wanted to blow the converter box off the side of the machine we were using. Suffice it to say, doing so is not Standard Lab Procedure.
