Abstract:
1. An NMR (nuclear magnetic resonance) apparatus, the apparatus comprising: a cryostat having at least one nitrogen tank for receiving liquid nitrogen, said cryostat defining a room temperature bore; a magnet system disposed in said cryostat; an NMR probehead disposed in said room temperature bore, said NMR probehead having a transmitting and receiving system; and a supply line, said supply line disposed between and connecting said nitrogen tank of said cryostat to said NMR probehead, said supply line disposed, structured and dimensioned to remove liquid nitrogen from said nitrogen tank and to guide that removed liquid nitrogen to said NMR probehead, thereby cooling said NMR probehead or parts of said NMR probehead to cryogenic temperatures, said supply line thereby having a first end disposed, structured and dimensioned for immersion into liquid nitrogen within said nitrogen tank and a second end connected to said NMR probehead, wherein said supply line has a supply line section extending outside of said cryostat between said first end and said second end.
