Course Description

This course focuses on the study of solving chemical analysis problems from a statistical point of view. After taking this course, students are expected to apply basic chemometric skills in analyzing data obtained in chemical practicum and research. The first part of the engineering lecture is designed using examples of significant test cases faced by chemists, especially those related to quantitative data of chemical analysis. The second part focuses more on understanding instrumental data analysis and experimental design.
