Also known as LOD or detection limit (DL), is the lowest amount of analyte in a sample that can be detected, but not necessarily quantitated as an exact value. The LOD may be expressed as: LOD = 3.3 * SD / S; ... Search for Limit of detection in these other databases too...

Given this critical level, the limit of detection (LD) is construed as the level that will lead to false non-detects with probability b. Common values for a and b are 1% and 5%. The proper values are of course problem-dependent.

The limit of detection, expressed as the concentration, , or the quantity, , is derived from the smallest measure, , that can be detected with reasonable certainty for a given analytical procedure. The value of is given by the equation...

The detection limit of an individual analytical procedure is the lowest amount of analyte in a sample which can be detected but not necessarily quantitated as an exact value.

Formally, the limit-of-detection (lod) is defined as the concentration of analyte required to give a signal equal to the background (blank) plus three times the standard deviation of the blank. So, before any calibration or sample measurement is performed, you must evaluate the blank.

F1.1. At low concentrations, an increasing variety of effects becomes important, including, for example, the presence of noise or unstable baseline, the contribution of interferences to the (gross) signal, the influence of any analytical blank used, and losses during extraction, isolation or clean-up. ... f.1 Introduction;

The limit of detection (LOD) for any analytical procedure, the point at which analysis is just feasible, may be determined by a statistical approach based on measuring replicate blank (negative) samples or by an empirical approach, consisting of measuring progressively more dilute concentrations of analyte.
