Les methodes permettant le controle de la qualite de l'eau ne sont pas assez precises pour mesurer les polluants presents a l'etat de traces. Les auteurs demontrent que la limite de detection (en dessous de laquelle les polluants ne sont plus detectes) ne doit pas etre utilisee pour censurer les ...

Why determine detection limits?A natural question to ask about any quantitative technique, including EELS in the STEM, is “How little of <x> can be observed?” Detection limits serve as a guide to what problems are solvable and what are the best techniques to analyze specific systems, e.g., EELS vs. EDXS vs. SIMS, etc.

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 ...

Detection Limits for Nanoscale Biosensors
Nano Letters, 2005We examine through analytical calculations and finite element simulations how the detection efficiency of disk and wire-like biosensors in unmixed fluids varies with size from the micrometer to nanometer scales. Specifically, we determine the total flux of DNA-like analyte molecules on a sensor as a function of time and flow rate for a sensor ...

Multivariate detection limits estimators
Chemometrics and Intelligent Laboratory Systems, 1996Abstract The theoretical development of the concept of detection limit in multicomponent systems has only begun very recently and its practical applications are limited to a few specific techniques such as emission spectrometry (ICP-OES) or high performance liquid chromatography (HPLC-DAD).

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.

Quantum-limited image detection
Optical Society of America Annual Meeting, 1991Image detection in low-light-level conditions is treated as a hypothesis-testing problem based on a finite set of samples, Z1,...,Z K , from a filtered 2-D Poisson process. Since it is not feasible to compute the joint probability distribution of Z1,...,Z K , a straightforward likelihood-ratio test is not a possibility.

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.
