The relatively clean spectrum of glass constituents enables the use of the JY 2000-2 without the need of the high resolution of the ULTIMA 2. The results show excellent agreement with expected results for all element, both major constituents and traces. The use of sequential internal standard has been shown to compensate for any viscosity differences between the samples and standards. The speed of analysis of less than 2 minutes for the 10 elements determined, and the detection limits achieved, are more than adequate for laboratories doing ordinary glass analysis. Although both acid and fusion methods were tried, afusion would appear to fulfil the requirements of full analysis in one sample preparation. If lower detection limits are required for some of the trace elements, then an HF acid digestion will be required as well.
