A small amount of tin which was contained in the surface of float process glass was determined by an X-ray fluorescence spectroscopy and by an electron probe microanalyser.<BR>The standard samples were prepared by mixing various amounts of stannous oxide with soda-lime-silica glass batch and melting at 1350°C.<BR>The content of tin was determined by phenylefluorone spectrophotometric method.<BR>The result of electron probe microanalyser measurements suggested that tin was contained in a layer of 10 μ depth from the surface of the float process glass and surface content of tin was 1.46%. The X-ray fluorescence analysis showed that the tin content in total mass was 0.010%. Since the distribution of tin in standard glasses was homogeneous the mathematical correction for the difference of distribution of tin gave good agreement of the results by the two methods.
