Residual Rb content is reported as a function of OP-cell surface temperature based on the elemental analysis of an ∼1.0 L Tedlar bag containing ∼0.8 L of HP gas mixture after the transfer from the OP-cell through Teflon tubing with an in-line filter without cryocollection. Rb content obtained on the presented setup with a thermoelectric cooling (TEC) oven (ref (15)) utilized 1/8 in. o.d. (1/16 in. i.d.) Teflon tubing transfer lines with the temperature sensor mounted on the outer surface of the OP-cell. Residual Rb content obtained with the “open-source” hyperpolarizer with a forced air (FA) oven utilized 1/4 in. o.d. (1/8 in. i.d.) Teflon tubing transfer lines with the temperature sensor monitoring oven air temperature (refs (14 and 19)).
