Abstract
An NMR measuring system comprising an NMR probe head (34) with a cooled NMR receiver resonator (35) is connected via a transfer line (19) to a cooling device for supplying two coolant loops with coolant at two different cryogenic temperature levels, wherein the transfer line (19) contains one coolant feed line and/or one coolant return line for each of the two coolant loops for cooling the NMR probe head (34), and where these feed lines and return lines terminate on one side in four preferably standardized connection points (7,11,12,16) of the cooling device and on the other side, facing the probe head, in a standardized cryo-coupling device (28) which in its turn can be connected to a matching also standardized cryo-coupling device (29) attached to the probe head. The cryo-coupling device (29) in its turn is connected to the coolant feed lines (30,32) and coolant return lines (31,33) of the two coolant loops in the NMR probe head (34), and together with the coolant feed lines and coolant return lines of the transfer line they form two coolant loops. In this way, a common NMR measuring system can be modified in a simple and undemanding fashion such that completely different CRPs wi…
