WebInstrument Detection Limit (IDL) is a statistical measurement of analytical sensitivity that considers the precision of a measurement. It characterizes the amount of analyte (sample concentration or amount on-column) required to be 99% confident that a measured signal is real and not baseline noise. As an analyte’s level approaches the method ... WebLimit of detection (also called detection limit) – the smallest amount or concentration of the analyte in the test sample that can be reliably distinguished from zero . Decision limit (CC α ) – the concentration level, as determined by the method, at which there is a probability α (usually defined as 0.05 or 5%) that a blank sample will ...
