Analytical chemistry

Number：204 48740

Time: Fri. 8:10~10:00

Classroom: R315

Course description:

Sophomores, Juniors and seniors in the Dept. of Geosciences are all welcomed to take this course, which will approach quantitative analysis first from a classical point of view. Instructor will also review and expand upon the fundamental properties of some modern techniques, which are useful in geochemical analysis. This course emphasizes both theoretical and practical aspects of analytical techniques for geochemistry. Because laboratory experience is the essence of quantitative analysis, a course, “Analytical Chemistry Laboratory”, should be taken together to learn the basis of good laboratory practice. After taking this class, students, with a body of geo-analytical knowledge, will be able to design an experimental procedure to solve real or hypothetical problems. They will also learn how to independently accomplish general chemistry in a geochemical lab.

Course description:

This course, for undergraduate students, should be taken together with “Analytical Chemistry”. It consists of 8 laboratories. Laboratories include experiments in statistic, volumetric, gravimetric, and titrational methods of chemical analysis. Ion-exchange separation and instrumental methods will be also included for analyzing geochemical samples. The specific goals of this course are that each student will (1) learn the fundamental techniques of quantitative chemical analysis, (2) be familiar with analytical methods and apply them to environmental samples, and (3) learn the basis of good laboratory practice and develop confidence in laboratory abilities.
