Recently the spin–lattice relaxation time T1 of hyperpolarized (HP)-129Xe was significantly improved by using uncoated and Rb-free storage vessels of GE180 glass. For these cells, a simple procedure was established to obtain reproducible wall relaxation times of about 18 h. Then the limiting relaxation mechanism in pure Xe is due to the coupling between the nuclear spins and the angular momentum of the Xe–Xe van-der-Waals-molecules. This mechanism can be significantly reduced by using different buffer gases of which CO2 was discovered to be the most efficient so far. From these values, it was estimated that for a 1:1 mixture of HP-Xe with CO2 a longitudinal relaxation time of about 7 h can be expected, sufficient to transport HP-Xe from a production to a remote application site. This prediction was verified for such a mixture at a total pressure of about 1 bar in a 10 cm glass cell showing a storage time of T1 ? 9 h (for T 1 wall = ( 34 ± 9 ) h) which was transported inside a magnetic box over a distance of about 200 km by car.

Storage of nuclear magnetization as long-lived singlet order in low magnetic field
From The DNP-NMR Blog:
Storage of nuclear magnetization as long-lived singlet order in low magnetic field
This week I will catch up with some articles that were published in the Proceedings of the National Academy of Sciences that slipped through the crack.

[Question from NMRWiki Q&A forum] Where to find technical information on Varian and Bruker data storage formats?
Where to find technical information on Varian and Bruker data storage formats?
Hello, I would like to find detailed technical info on the binary data storage formats for Varian and Bruker. Could anyone point me to such resources?
I'm involved into a student project where NMR data will be displayed in the web browser. The first thing we'd like to explore is the possibility of processing 1D with javascript, but we first have to be able to read the original data...
I've looked through Varian manuals, but apparently the right one did not pop up in front of me :). Could you suggest -...
