Abstract

The production of enriched para- H2 is useful for many scientific applications, but the technology for producing and measuring para- H2 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- H2 enrichments of up to 99.99% at continuous flow rates of up to 0.4 SLM. We also discuss para- H2 storage and back conversion rates, and improvements to three techniques (thermal conductance, NMR, and solid hydrogen impurity spectroscopy) used to quantify the para- H2 enrichment.
