| DRAFT DEFINITION |
| Detection limit |
|---|
|
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. |

| Detection limit |

|
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. See also Orange Book Chapter 18.4.3.7 and 2.4. |
