The limit of detection, expressed as the concentration, $$c_{\text{L}}$$, or the quantity, $$q_{\text{L}}$$, is derived from the smallest measure, $$x_{\text{L}}$$, that can be detected with reasonable certainty for a given analytical procedure. The value of $$x_{\text{L}}$$ is given by the equation $x_{\text{L}}=\overline{x}_{\text{bi}}+k\ s_{\text{bi}}$ where $$\overline{x}_{\text{bi}}$$ is the mean of the blank measures, $$s_{\text{bi}}$$ is the @S05911@ of the blank measures, and $$k$$ is a numerical factor chosen according to the @C01246@ desired.
