Metropolitan State College, Colorado August 13-14, 1983 STATISTICAL METHODS FOR CHEMISTS: An i n t r o d u c t i o n t o a w i d e v a r i e t y of s t a t i s t i c a l m e t h o d s in c h e m i s t r y Faculty: Dr. Robert A. Crovelli, Mathematical Statistician, Resource Appraisal Group, U.S. Geological Survey, is Project Chief of Probabilistic and Statistical Methodology for Petroleum Resource Appraisal. Course Synopis: The course stresses how to think statistically by studying the assumptions and applications of statistical methods in chemistry. The student will learn how to use statistical methods and the appropriate formulas without an emphasis on proofs and arithmetic. Topics are probability distributions, descriptive statistics, sampling theory, statistical estimation, tests of hypotheses, nonparametric statistics, analysis of variance, design of experiments, factorial experiments, linear regression and correlation, multiple linear regression, and statistical computer packages. This intensive course is designed for the chemist who is a beginner in the application of statistical methods. The course text and lectures are carefully coordinated so that the student finishes the course with a complete printed guide for future reference.

Retirees LABORATORY AUTOMATION: Micro-, Mini-, or M i d i - C o m p u t e r s : H o w t o c h o o s e . . . a n d u s e . . . t h e right a u t o m a t i o n e q u i p m e n t Faculty: Dr. Raymond E. Dessy, Professor of Chemistry, Virginia Polytechnic In stitute and State University, is an international authority on minicomputers and microprocessors and their applications to chemical research. He is the author of over 1 00 publications. Assisting Professor Dessy will be members of the VPI and SU Chemistry Department Instrument Design and Automation Research Group. Course Synopis: The course shows, through the use of governmental and industrial examples, how to decide on proper laboratory automation equipment under specific circumstances and how data acquisition and utilization can be accomplished. Your staff scientists will learn the basic philosophies and jargon involved, from simple data logging through fully implemented real-time foreground/background computer systems involving multi-programming and multi-tasking. Utilization of dedicated microprocessors and minicomptuters as intelligent n o d e s with minimum configuration t o hierarchical networks involving maximum system configuration is covered. The course is intended for scientists who are involved with laboratory automa tion at either t h e bench or managerial level. Some exposure to programming a computer in any language is helpful but not essential. Participants are encouraged to bring their own automation problems with them for discussion with the staff and other course participants. FEE*: ACS Members, $495; Nonmembers, $525.

Michael Thurman, Research Hydrologist, Organic Research Group, U.S. Geological Survey, Denver, Colorado, is active in organic geochemistry, analysis of organic substances in natural and polluted waters, and the movement of organic pollutants in ground water. Course Synopsis: The course discusses the amount of organic solutes in natural and polluted waters with special emphasis on ground waters. The classes of organic c o m p o u n d s are described including: carboxylic acids, amino acids, carbohydrates, humic substances, and hydrocarbons. Pollutant organics are discussed and their interactions with sediment, water, and aquifer materials. The role of geochemical processes such as adsorption, oxidation/reduction, precipitation, and metal complexation is addressed. The methods of analysis of organic substances, liquid and gas chromatography, mass spectroscopy, nuclear magnetic resonance, as well a s other spectroscopic methods are explained. The final session includes problem solving by various analytical approaches A BA/BS degree in chemistry
is
required.

beginning or middle of the 16th centu ry (13). In addition, the Virgin Mary's robe is entirely painted in Prussian blue, a pigment that was invented in Germany around 1704 and not widely used by artists until a considerably later time (14). Thus the FTIR analy sis of the paint materials supports the judgment of the art conservator; i.e., the painting is either a very heavily re worked fragment or an imitation of an early work. As we have demonstrated, FTIR is a practical method for analysis of both organic and inorganic painting materi als. Although further testing of this painting would be necessary to arrive at a final statement regarding authen ticity, FTIR can quickly provide infor mation on complex painting materials in extremely small samples. The painting remains intact for further study by scientists, historians, and students. It is our hope t h a t further research will be conducted to classify typically used artists' pigments, oils, varnishes, and other media according to their IR spectra. FTIR may also help the conservator identify modern substances applied to art objects and provide an understanding of the alter ation of materials as they age.
