Use of Stabilized Plasma Arc Excitation in Determining the Element Boron in Gasoline

Abstract

This report describes the use of a stabilized plasma arc source in the quantitative spectrographs determination of boron in gasoline. The advantage is that the plasma arc requires no preliminary sample preparation other than addition of nickel hexoate internal standard in ethyl alcohol buffer solution. The National Bureau of Standards # 1063 menthyl borate may be used for preparing calibration curves. The method is applicable to the determination of boron in the range of 0.0001 to 0.0010 per cent. The standard deviation is 0.000055 per cent; the coefficient of variation is 8.1 per cent.
