Of connecting cryocooling sytems to nmr nmr - probe heads in an nmr - measuring device with a cooling system and transfer line

摘要

A nmr - measuring device with a nmr - probe head (34) with a cooled nmr - reception resonator (35) is connected via a transfer line (19) with a cooling device for the purpose of charging of two cooling circuits with coolant on two different cryogenic temperature level, wherein the transfer line (19) in each case a coolant feed line and / or a coolant return line for each of the two cooling circuits for mmr - probe head (34) which, in the cooling device in four, preferably standardized connections open, and the samples head from one end in a standardized cryostat the clutch open in front of the direction (28), to which a matching, likewise standardized the cryogenic clutch against the direction (29) can be docked, into which the corresponding cooling supply lines (30, 32) and coolant return lines (31, 33) for the two cooling circuits in the nmr - probe head (34) open, whereby the cooling of the invention, the cooling supply lines and return lines to the terminals in the cooling device as well as the corresponding cooling supply lines (30, 32) and coolant return lines (31, 33) in the nmr - probe head (34) are wired in such a way that, in principle, two cooling circuits can be maintained. Thus it is possible to simply and readily a conventional nmr - measuring device modified so that a completely different crps with any desired construction of the cooling devices without any adaptation with the smallest possible amount of time can be coupled to one another.
