In the article cited above, the explanation of limit of quantification (LoQ) given in section 4.3.8.iv.3 (page 565) was misstated.

The correct text reads:

Limit of Quantification (LoQ) is the lowest amount of measurand that can be quantitatively determined with acceptable precision and trueness, under stated conditions [1]. It may be equal to or higher than the Limit of Detection (LOD) but will not be lower. There are multiple formulas in the literature that can be used to estimate LoQ [2-4]. These formulas compute a value used to verify that observed total error (TEo, calculated as bias + 2SD) is less than allowable total error (TEa). Multiple low concentration samples will need to be tested to determine the lowest measurand concentration at or closest to TEa.
