The slope used in these equations is equivalent to instrument sensitivity for the specific
analyte, reinforcing the fact that LOD/LOQ are expressed in units of analyte concentration
(e.g. mg/ml) or amount (e.g., mg). Since the LOD and LOQ are functions of instrument
sensitivity, these values, when defined this way, are not universal properties of the method
transferable from instrument to instrument, or from analyte to analyte.
