The limit of detection (LOD or LoD) is the lowest signal, or the lowest corresponding quantity to be determined (or extracted) from the signal, ...
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output.
Considering detection limit, both TCD and FID reach low concentration levels (inferior to ppm or ppb). [2] Both of them require pressurized carrier gas (Typically: H 2 for FID, He for TCD) but due to the risk associated with storing H 2 (high flammability, see Hydrogen safety), TCD with He should be considered in locations where safety is crucial.
