Building standard curve and liner range, the limit of detection and limit of quantitation are determined. The precision, reproducibility and recovery of 916 in animal serum are tested.
建立了标准曲线及线性范围,确定了916在动物血清中的检测限和定量限。

This value represents the limit of quantitation for both ions.
此值代表此两种离子的量检测限。
Rather the quantitation limit is shown to be sufficiently low by the analysis of samples with know concentrations of analyte above and below the quantitation level.
而是,通过分析含有高于和低于必需的定量水平的、已知待分析物浓度的样榀,以显示定量限度足够低。
Whatever method is used the quantitation limit should be subsequently validated by the analysis of a suitable number of samples known to be near or prepared at the quantitation limit.
无论用什么方法,均应该在随后通过分析适当数量的、已知接近或制备于定量限度的样榀,来验证定量限度。
