国际上先进的分析实验室都极为重视样品前处理工作 ,采样和样品前处理投入约占全部分析和数据处理投入的 67%。样品前处理设备应该是独立的工作系统 ,而非分析仪器的一个附件。因为分析仪器如 ICP光谱仪的性能好坏 ,主要影响到分析结果。而样品前处理的情况则不仅会影响分析结 Internationally advanced analytical laboratories attach great importance to the sample pretreatment, sample and sample pretreatment inputs account for about 67% of all the analysis and data processing. The sample preparation equipment should be a separate working system rather than an accessory to the analytical instrument. Because of the performance of analytical instruments such as ICP spectrometer, the main impact on the analysis results. The sample pretreatment will not only affect the analysis of the junction
