The purpose of this page is to provide current information about CH 424, Instrumental Analysis, to students and any other interested parties.
The reason all this is interesting...
Consider the painting by Arthur Hughes entitled Fair Rosamund (1854). This is an important piece for (at least) three reasons: 1) its real pretty; 2) the subject is historical: Eleanor of Acquitaine finding her husbands (King Henry II) mistress Rosamund in a secret garden (OK, maybe only I find that part interesting...), and 3) for us the most important, the fact that the painting is so striking because of the new oil-based paints made by the chemists of the 19th century. Particularly note the electric greens and purples. These were simply not available to earlier artists. The chemistry behind these paints led, in part, to the development of spectroscopy as a discipline.
The purpose of this course is to provide students with knowledge of various modern methods of instrumental analysis in order to prepare them for industrial or academic careers. The course stresses quantitative rather than qualitative analysis, since this aspect of many of the techniques is covered in other chemistry courses. The material presented and the depth of treatment are intended to adequately prepare students for the ACS Graduate Placement Examination in Analytical Chemistry (Instrumentation) upon entry to graduate school. Additionally, students will receive instruction on the basics of scientific report writing.
