In the method previously described for the determination of trace amounts of beryllium in silicates, a double fusion of the sample with sodium hydroxide was made and beryllium was then determined Auorimetrically in the filtrates with morin as reagent'. This procedure gives satisfactory results when
## Abstract The quantitative CE analysis of fluorine and monofluorophosphate in toothpastes is described. Separation is performed using a Waters CIAβPak chemistry kit with Waters Electro Osmotic Flow Modifiers on a CE instrument from Spectra Physics (Spectraβphoresis 500) at elevated temperatures u
Prompt gamma rays from inelastic scattering and nuclear reactions induced by alpha particles have been used to determine fluorine in cements. The method is suitable for fluorine concentration of about 0.1% but is sensitive to parts per million. The precision of the method is determined by the homo
