We describe an experimental approach that combines multidimensional NMR experiments with a steadily renewed source of laser-polarized 129 Xe. Using a continuous flow system to circulate the gas mixture, gas phase NMR signals of laser-polarized 129 Xe can be observed with an enhancement of three to f

Laser-polarized noble gases such as 3 He or 129 Xe exhibit a nuclear spin polarization exceeding the equilibrium nuclear spin polarization by orders of magnitude, resulting in a corresponding sensitivity gain in NMR experiments. Recent developments in the application of laser-polarized 129 Xe are re
Laser-polarized 129 Xe dissolved in a foam preparation of fresh in blood found 4.5 { 1 s in red blood cells and 9 { 2 s in human blood was investigated. The NMR signal of 129 Xe dissolved plasma (18). This experiment used thermally polarized 129 Xe in blood was enhanced by creating a foam in which t
