2 Basic terms

2.1 The detection limit detectionlimit The lowest concentration cL (or at a certain minimum degree of confidence signal analysis by a specific analytical method can detect distinguished xL determined Quality qL). cL & (or qL) = (xL-xb)/m = k · sb Where. xL --- minimum mean signal analysis; xb --- blank signal average; m --- a calibration curve in the low concentration range of the slope; k --- factors associated with confidence; Sb --- blank signal standard deviation value. Note. The International Federation of Pure and Applied Chemistry (IUPAC) regulations, xb and Sb experiments with enough number of measurements n≥10 determined. Recommended k = 3, in Under normal conditions the measured value to comply with, a confidence level of 99.73%. Three times the standard deviation of the blank signal values \u200b\u200bcorresponding to the concentration (or mass) is seized The limit. 2.2 Limit of quantification quantificationlimit The lower limit of a component quantitative analysis method that can actually be measured. Note. IUPAC prescribed to 10 times the standard deviation of the blank signal values \u200b\u200bcorresponding to the concentration (or mass) of the limit of quantification. 2.3 Sensitivity sensitivity Signal to be measured changes in response to the amount of concentration (or mass) is a unit of measurement of the object caused. Note. You can also be understood as the slope of the calibration curve. 2.4 Accuracy accuracy Under certain conditions the measurement value was measured by measuring its true value closeness. Note. commonly referred to as the true value refers to the theoretical true value (such as the angles of a triangle equals 180 °), conventional true value (of the International Conference, the International Organization for Standardization, or on the public Recognize the magnitude) and relative truth value (such as the magnitude of the reference material certificate given). It excludes all defects on the measurement time by measuring the resulting sound ......
