The separation was carried out in less than 20 min on Metrosep Carb 1 with O.lmol/L NaOH as the eluent. The cation-exchange separation of the [ F]FCH reaction mixture utilizing nonsuppressed conductivity detection is shown in Figure 10.335. Besides nanomol quantities of the [ FjFCH radiotracer, considerable amounts of the DMAE reactant and trace levels of calcium impurities were detected in this reaction mixture. Using Metrosep C4 as the stationary phase and a mixture of nitric acid and dipicolinic acid as the eluent, the total analysis time is less than 15 min.
