Abstract

The production of enriched para-H-2 is useful for many scientific applications, but the technology for producing and measuring para-H-2 is not yet widespread. In this note and in the accompanying auxiliary material, we describe the design, construction, and use of a versatile standalone converter that is capable of producing para-H-2 enrichments of up to >= 99.99% at continuous flow rates of up to 0.4 SLM. We also discuss para-H-2 storage and back conversion rates, and improvements to three techniques (thermal conductance, NMR, and solid hydrogen impurity spectroscopy) used to quantify the para-H-2 enrichment.
