[交流] 【求助完毕】-LOQ拼写的澄清?

LOQ:
limit of quantitation
limit of quantification

到底哪个是对的?二者有什么区别吗?请高手指点!

limit of quantitation (quantitative detection limit; limit of determination)
(LOD) The smallest detectable concentration an analytical instrument can determine at a given confidence level. IUPAC defines the quantitative detection limit as Cld = ks/m, where k is 10, s is the standard deviation of instrument readings taken on a "blank" (a solution with zero concentration of analyte), and m is the slope of a plot of instrument response vs. concentration, as calculated by linear regression.

Limit of Quantification (LOQ)
The LOQ, is the lowest concentration of a residue that can be identified and quantitatively measured in a food sample using an analytical method that has been validated with specified accuracy and precision.

这里面可以看出区别了:一个是最小检测浓度(不一定能量化),一个是最小量化值。
