Sample solution preparation

The quality control of AAS measurement such as the test preparation, the standard solution and sample preparation method, the sample analysis and the data processing were introduced.

介绍原子吸收光谱法检测过程中实验准备、标准溶液和样品制备方法、样品分析及数据处理等几个环节的质量控制措施。

The main sources of measurement uncertainties were from sub-uncertainties of sample preparation, calibration solution preparation, calibration curve fitting and instrument measurements, etc.

分析了不确定度的重要来源，包括样品制备、标准溶液配制、标准曲线拟合和仪器测量过程等引入的不确定度分量。

The experimental instrument, sample preparation and determination method of the trace element Se in solution by total reflection X-ray fluorescence analysis are described in this paper.
