These include the instrument detection limit (IDL), the method detection limit (MDL), the practical quantitation limit (,PQL,), and the limit of quantitation (LOQ). Even when the same terminology is used, there can be differences in the LOD according to nuances of what ,definition, is used and what type of noise contributes to the measurement and calibration.

Define Practical quantitation limit. (,PQL,) means the lowest level that can be reliably measured during routine ,laboratory, operating conditions within specified limits of precision and accuracy. [Refer to the ,PQL, guidelines referenced in subsection 62-780.100(5), F.A.C., for guidance.]

The ,PQL, is operationally defined as the concentration at which the instrument response signal is 100/α times its standard deviation (e.g., for a 10% relative standard deviation (R.S.D.) α = 10). The response signal is defined as the ratio of analyte to internal standard peak areas. 95% confidence limits for the ,PQL, are also derived.

covers the ,PQL,. It comes down to what the ,laboratory, feels comfortable signing their name to, confidently, on a daily basis. The final arbiter of the ,PQL, is the concentration of the lowest standard analyzed for that sample set. Laboratories almost universally have set their ,PQL, to the concentration of that lowest standard.
