C30J [CHEM3001] CHEMICAL ANALYSIS II
(4 Credits) Semester 2 Level III

Pre-requisite: C20J (Pass or Fail, but not Failed Absent)

Syllabus:

Classical Methods. Gravimetric methods of analysis. The properties of electrolytes and their effects on solubility. Properties of colloids. Practical methods.

Analytical Methods for Metals. Atomic Absorption, Emission and Fluoresence Spectroscopies. Basic experiments and instrumentation. Methods of atomisation and practical considerations. Xray Fluoresence Spectroscopy: courses and detectors, sample preparation, interpretation of spectra-interferences and enhancements. Instrumental Neutron Activation Analysis: the basic experiment, instrumentation, applications and limitations.

Chromatography: A review of the principles of chromatography. Sampling for chromatography. Further applications of GC, GC detectors. Liquid chromatography: HPLC in its various forms, instrumentation, columns, detectors. GC-MS and other hyphenated systems.

The analysis of real samples. The analysis of trace vs major components. Sampling theory, contamination, and errors associated with sampling. Inter-laboratory calibration/testing exercises. The Professional Analyst.

Evaluation:

In course test and report 20%

Practical work 20%

One 2-hour written paper 60%

Practical work is assessed throughout the duration of the course. Students whose practical work is considered to be unsatisfactory are required to sit a practical examination of not more than 6 hours duration. Candidates must provide the ORIGINAL notebooks and reports of their laboratory work at the practical examination. These must be certified by the laboratory course supervisor and may be taken in consideration by the examiners.
