Determination of fluorine in milk samples via calcium-monofluoride by electrothermal molecular absorption spectrometry

► F determination via MAS of CaF at 606.440 nm using HR-CS-ETAAS is done. ► There is no need to use any modifier and to cover the platform/tubes. ► A good linearity is maintained up to 0.1 μg of F. ► The limit of detection and characteristic mass for the method are 0.26 and 0.13 ng, respectively. ► The method is simple, fast, accurate and sensitive.
