T1 - Determination of perfluordecalin in consume care products by use of GF-HR-CS-MAS N2 - The introduction of HR-CS-MAS instrumentation, as it is shown in Fig. 1, provides a new way for the determination of non-metals including fluorine via molecular absorption. We present a sensitive and fluorine-specific method for total fluorine determination in fifteen consume care products in which perfluordecalin were declared (nail polishes, eye shadows and body creams). After pyrohydrolytic digestion of samples, fluorine content was determined by GF-HR-CS-MAS. Calcium was used as a molecule forming element and the molecular absorption of calcium monofluoride (CaF) at the wavelength 606.440 nm was used for its quantification. No matrix effect was observed. Analytical signal depends only on the fluorine concentration and therefore pure sodium fluoride NaF was used as calibration standard. The use of zirconium oxide nanoparticles as permanent modifier improves the limit of detection (from 0.2 to 0.1 ng) and characteristic mass (from 0.10 to 0.05 ng) from a previous reported method. These results were also compared with ISE method (standard DIN 51-084) and no significant difference was found T2 - Bremen Flourine Days CY - Bremerhafen, Germany DA - 03.07.2016 KW - Perfluordecalin KW - Consume care products KW - High resolution continuum source absorption spectrometry PY - 2016 AN - OPUS4-37481 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
