detektiorajat

Detektiorajat refers to the detection limits of a measuring instrument or analytical method. This limit represents the smallest amount or concentration of a substance that can be reliably distinguished from a blank or background signal. Below the detection limit, the signal is too low to confidently assert the presence of the analyte. It is crucial to understand that the detection limit is not the same as the limit of quantitation, which is the lowest concentration that can be measured with acceptable precision and accuracy. Different methodologies exist for determining detection limits, often involving statistical analysis of blank samples or a series of known low-concentration samples. Factors influencing detektiorajat include the sensitivity of the detector, the noise level of the instrument, and the specific analytical procedure employed. Reporting results below the detection limit is typically done by stating "less than the detection limit" or similar phrasing, rather than assigning a specific numerical value.
