kvantifieringsgränsen

Kvantifieringsgränsen is a term used in analytical chemistry and other scientific fields to denote the lowest concentration of a substance that can be reliably detected or measured by a particular analytical method or instrument. It is also referred to as the limit of detection (LOD) or detection limit. The quantification limit, often denoted as LOQ, is a related concept that represents the lowest concentration of an analyte that can be quantified with acceptable precision and accuracy. While the detection limit indicates whether a substance is present, the quantification limit indicates how much of it is present within a certain margin of error. Establishing these limits is crucial for determining the suitability of an analytical method for a specific application, such as environmental monitoring, pharmaceutical analysis, or food safety testing. Factors influencing the quantification limit include the sensitivity of the instrument, the background noise, the sample matrix, and the chosen analytical procedure. Different methods will have different quantification limits, and the choice of method often depends on the required sensitivity for the analysis. Exceeding the quantification limit ensures that the measured value is statistically significant and not merely a result of random fluctuations or interference.
