The detection limit of an instrument should be differentiated from sensitivity. The detection limit reflects the smallest flow of sample or the lowest partial pressure that gives a signal that can be distinguished from the background noise. One must specify the experimental conditions used and give the value of signal-to-noise ratio corresponding to the detection limit. |

Orange Book Entry
The detection limit reflects the smallest amount of sample or the lowest partial pressure that gives a signal that can be distinguished from the background noise. It is recommended that a signal-to-noise ratio of 2:1 be used to define the detection limit.
