Efficiencies of [18F]fluoride elution using different eluent solutions measured in the intermediate vial system. Elutions were performed with two plugs of eluent solution (12.4 µL total volume).
| Eluent (in DI water) | Elution efficiency based on trapped activity (%) |
|---|---|
| 0.01 M K2CO3 and 0.05 M K222 | 89 ± 7 (n=8) |
| 0.08 M TBAB | 92 ± 8 (n=2) |
| 0.15 M NaCl (Saline) | 96 ± 5(n=10) |
| 0.01 M K3PO4 and 0.07 M 18-Crown-6 | 88 (n=1) |
| 0.18 M K3PO4 | 90 (n=1) |
| 1.19 M K3PO4 | 100 (n=1) |
