DOI: 10.1002/jssc.201200537 Europium(III) derivative formed by reaction of the europium ion with a fluorinated β‐diketonate reagent and a neutral donor. The resulting non‐polar, thermally stable, and luminescent derivative partitions into cyclohexane upon formation and can be subjected to high‐resolution capillary gas chromatography. This approach is used to separate derivatives of lanthanides that are adjacent to one another in the periodic table. In addition, an on‐fiber SPME derivatization/concentration GC/MS method that uses a fiber preloaded with the same β‐diketonate reagent is described for the analysis of beryllium(II) ion.
