(1) the sample is diluted 50 times with 5% HNO3.
用5%的硝酸将样品稀释50倍。 50ppb (100ppb) is prepared for each sample.
ICP-MS标准溶液(10 or 100ppb)(1),再为每个样品准备5ppb, 10ppb,20ppb, 50ppb (100ppb)标准液。After drawing the standard calibration curve,you can
以5%的硝酸为基准,然后绘制标准曲线图,通过分析先先前浓缩的样品你可以得到相应的浓度。
Be careful (3) The sample`s metal content should be limited point (2) in the range of the green curve
注意(3)样品的金属含量应该限制在(2)中的绿色曲线之内。
If you know the approximate range of Metal content (1) the dilution ratio and (2) to adjust the range of the curve,you can enables to enhance the accuracy.
如果你知道大概的金属含量 (1)稀释的比率 以及 (2)调整曲线的范围,那么你可以提高精确度。
