The quantification of fluorine in small traces is a challenge for instrumental analysis. One powerful tool is the quantification of fluorine via molecular bands, such as calcium or gallium fluoride compounds. Molecular absorption spectrometry (MAS) with contrAA 800 is a versatile and promising method for instrumental analysis in the 21st century.

 
The unique design of the contrAA 800 high-resolution continuum-source atomic absorption spectrometer (HR-CS AAS) allows absorption bands of molecular vibrations and rotations in the 185-900 nm range to be detected and quantitatively evaluated in addition to atomic absorption lines. By adding a suitable molecule-forming reagent, molecular compounds are generated under optimized conditions. One or more molecular absorption bands in the spectral observation window can then be used for analytical evaluation and quantification of an analyte such as fluorine via CaF or GaF molecules. The graphite furnace technique allows very sensitive quantification in the µg L-1 range using CaF or GaF molecule bands in suitable matrices. We will present compelling sample preparation techniques to access the most demanding matrices for fluorine analysis.
