Chromatographic Measurements, Part 4: Determining LOD and LOQ
In sections 6 and 7 of Q2 (R1), three different methods are listed to determine method limits. By method limits, we mean the limit of detection (LOD, also called detection limit, DL) and the limit of quantitation (or quantification, LOQ; also called lower limit of quantification, LLOQ or quantitation limit, QL).
