我们无需去证明方法的灵敏度有多高,只需要保证我们设定的特定限度满足方法准确定量的要求即可。 随着这个观点的转变,将使得LOD/LOQ从一个未知的浓度(需要估算或一系列实验来摸索测定)变成了一个已知的浓度(特定的满足使用要求的浓度),从解题变成了证明题,使得大家一下子变得轻松了许多。 实际上这个观点,在国内很多人...

LOD and LOQ using data they still have or they can collect at zero cost. Not to present a state-of-the-art review of the literature about this subject. IUPAC definition The minimum single result which, with a stated probability, can be distinguished from a suitable blank value. The limit...
Determination of Limits of Detection and Limits of Quantitation.1 The Figure taken from their document illustrates the distinction of LoB, LoD and LoQ values. Typically, LoQ will be found at a higher concentration than LoD, but how much higher depends on the specifications for bias and ...
The MDL is a procedure whereby the LOD is established with the analyte of concern in a complex matrix. The procedure establishes a relationship between detectability and analytical precision (i.e., an indicator of the reproductibility of a determination). ...
通过配制空白和标曲溶液来测试，可分别获得响应值偏差和标曲的斜率，然后计算得到LOD/LOQ。
