Figure 5: Decay of 129Xe signal during continuous device operation.

From: An optimized microfabricated platform for the optical generation and detection of hyperpolarized 129Xe

Figure 5

(a) Device operated continuously under conditions similar to those employed in first-generation device: 200 Torr Xe at natural isotopic abundance (26.4% 129Xe), 400 Torr N2. (b) Device operated continuously under 800 Torr Xe at natural isotopic abundance, 800 Torr N2. (c) Zoom-in on pump chamber signal (same data as in b). (d) Zoom-in on probe chamber signal (same data as in b). In all cases, the devices were continuously operated under a total gas flow rate of 5 μL/s and a temperature of approximately 140 °C. Pump chamber signals are shown in blue and probe chamber signals are shown in red.
