Abstract

A gas chromatographic method for determination of ethanol in an fluorodeoxyglucose (FDG)-18 solution was developed. The pre-validation tests were made to test some parameters. Three samples in the concentration of 400, 4000 and 7200 ppm, respectively were analyzed using the novel methodology. The results of the technique were not good. Although the method seems to be capable to identify ethanol in solution, the pre-validation demonstrated a problem in the technique.  The linearity results showed an R2 of 0.66. Further tests must be made to implement this technique in a daily routine.
 
Key words:  Validation, chemical analysis, quality control
