An efficient and compact para-hydrogen catalytic converter system for PHIP studies is described. The system consists of local production of small predetermined amounts of hydrogen and an efficient and convenient catalytic converter at ambient pressure. In this system, the enhancement factor per concentration was c.a. 2,100 and c.a.3,500 for 1H- and 13C- ALTADENA studies, respectively. The system proved to be an excellent source of para-hydrogen for PHIP studies in a hospital/MRI suite environment.
