Abstract Instrumental analysis courses involve a wide range of knowledge, high level of difficulty difficulty in understanding, and high requirement of practical skills. Therefore, it is worth exploring how to introduce new perspectives to refine and consolidate teaching content, and enhance learning effectiveness. From the perspective of the “calibration curve”, this paper intuitively explains the definition of the analytical performance parameters and their relationship such as sensitivity, characteristic concentration, characteristic quality, limit of detection, and limit of quantitation. It summarizes the types of interference in instrumental analysis and their elimination methods using the calibration curve as the integration point, explores their commonalities and essence, proposes the approaches and strategies, and provides a new perspective of “numerical and graphical integration” and “application-oriented” for the learning of instrumental analysis courses. This perspective helps to integrate key knowledge points and cultivate students’ awareness and thinking methods of “learning for application”.
