A statistical approach for evaluation of PCR results to improve the practical limit of quantification (LOQ) of GMO analyses (SIMQUANT)

European Food Research and Technology, 2008
The predominant approach for quantification of genetically modified organisms (GMO) is the application of quantitative real-time PCR. However, for a large number of processed food and feed products, this approach is unsuitable, because they contain low amounts (mass) of amplifiable DNA. Here we present a novel approach, “Single molecule quantification”

Detection Limit (LOD) and Limit of Quantification (LOQ) Using Microscopical Methods in Asbestos Analysis

2021
Optical methods (light or electron microscopy) are, in most cases, the basis for measuring the asbestos concentration either in air or in materials. The individual methods are described in a variety of guidelines or standards. The definition of terms like detection limit and analytical sensitivity have led to numerous discussions, driven by the fact ...
