Over the last couple years, Patrick Hansen has made steady progress on the gas chromatography system used to separate H2, HD and D2 in Dr. Whisnant's lab. Building on the work of Laurence Lewis, Travis Kelley and Ryan Burke, Patrick has now put the system in a state where it can be reliably used to assay gas from the distillery before it is sent to JLab for use in polarized target production.
He has reviewed the literature and found that no one else has obtained results as good or had been so quantitative about the interpretation of the results. Thus, at the moment, he is busy writing his results up for publication.
Paper in progress. Stay Tuned.
