In analytical chemistry, the detection limit, lower limit of detection, or LOD (limit of detection), is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) within a stated confidence limit (generally 1%). The detection limit is estimated from the mean of the blank, the standard deviation ...

The detection limit indicates the value of a measuring system, up to which a measurement (of gas) can be reliably detected with the measuring system. The reliability of the detection is defined by a statistically specified so-called confidence interval. In circumstances where the measurement values are under or over the detection limit, they are de...
