The LOD is based on the relationship between the gross analyte signal St, the field blank Sb, and the variability in the field blank ¦Ò. The limit of detection was defined by the extent to which the gross signal exceeds Sb. St-Sb = K¦Ò. The corresponding limit of detection expressed in concentration units is derived from the calibration function. The content at the limit of detection (cD, DÊÇϱ꣬¾ÍÊÇÓÃŨ¶È±íʾµÄ¼ì³öÏÞ) followed from the analytical function, cD= (St-Sb)/s = K¦Ò/s, where ¦Ò was the standard deviation of the blank solution, s was the slope of regression line, K was used as 3. |
