Detection limits are highly controversial in practice despite decades of developmental efforts by analytical scientists and regulators. This high resistance to obtaining effective and accepted detection limit solutions indicates our collective failure in how we traditionally approach this problem.

Detection Limits in the Far Infrared
Space Science Reviews, 1995The advent of far infrared arrays will change fundamentally the means of analyzing observations in this spectral region. Sources much fainter than traditional “confusion limits” will be extracted from images by using computer algorithms similar to CLEAN or DAOPHOT.

Detection Limits and Selectivity in Electrochemical Detectors
Analytical Chemistry, 1988Electrochemistry provides a powerful set of tools for analysis. Its power derives from the fact that electrochemistry is inherently chemical in nature. This instrumentation article describes developments in current-carrying electrochemical detectors.

Nondetects, Detection Limits, and the Probability of Detection
Journal of the American Statistical Association, 1991Abstract When chemists cannot quantify the concentration in a field sample, they report nondetect instead of a numerical measurement. A data analyst faced with environmental data containing nondetects might assume that all nondetects are zeros, all nondetects are smaller than the smallest detect (numerical measurement), or, if a detection limit is ...

Health Physics, 1992
Detection limit parameters such as the minimum detectable concentration have been widely discussed in the literature for more than 30 y. Misunderstanding and misapplication of these parameters continue to be widespread and, indeed, even encoded into computer programs, especially those developed in recent years for use with PC-based analyzer boards ...

Residue analytical limit of detectability
1965Determining how small an amount of a given pesticide or drug can be detected in plant or animal tissue has a profound effect on the commercialization of the compound being investigated. This effect lies within the complexities of governmental administration of pesticide and drug regulations, and is not a subject of this discussion.

The Limits of Detecting Abnormalities with Scanning
Australasian Radiology, 1967SUMMARYA theoretical comparison is made between two different criteria of statistical significance for detecting abnormalities in a scan. Criterion I utilizes as much of the available information content as possible, while Criterion II is applicable to visual reading of a photoscan or colour‐scan. The limits of detecting abnormalities with Criterion II

Handling the limit of detection by extrapolation
Statistics in Medicine, 2012A general method of estimation with a variable observed subject to a limit of detection is introduced. It is based on extrapolation of the estimates obtained by increasing the limit of detection. Theoretical arguments support the method in some special cases, and it is explored by simulations.
