In analytical chemistry, performance evaluation parameters for quantitative analysis methods include the spiked recovery, relative standard deviation, calibration curve and its correlation coefficient, linear range, error bar, limit of detection, sensitivity, selectivity, stability, etc. A deep understanding and proficient application of the above parameters are fundamental competencies for professionals in analytical chemistry. However, less than half of the students possess an adequate grasp of these common evaluation parameters, and could not distinguish parameters with similar meanings from the questionnaire survey for most senior undergraduates and postgraduate students. This deficiency is attributed to existing textbooks that merely introduce basic concepts of these parameters without illustrating their practical applications. Additionally, no comprehensive literature has systematically presented examples of how to apply these parameters. This paper carefully selects multiple cutting-edge articles from the highly-cited journal Analytical Chemistry, to vividly and thoroughly explain the standard applications of each evaluation parameters, replacing the previous one-dimensional theoretical descriptions. The goal of this work is to guide students in gaining a deep, intuitive understanding of how to effectively evaluate analytical methods and results based on these parameters, and to enable proficient and accurate expression in future scientific research. This paper aims to serve as a reference for improving the scientific and practical aspects of teaching evaluation parameters.
