A sample preparation method with lowdilution factor has been applied to the analysis of geological samples by X ray fluorescence spectrometry.
研究制定了在X射线荧光光谱分析中适用于多类型地质样品的低稀释比制样技术。

The fusion of samples is performed in graphite crucibles using lowdilution fusions with mixed flux. The calibration is done by use of synthetic standards.
样品用石墨坩埚、混合熔剂低倍稀释熔融，用人工标样作为校准标准。

When dilutionless drawing cann't be executed in one step, lowdilution drawing can be used and the cut-off grade can be gradually raised towards dilutionless drawing.
