Maximize your Kuderna-Danish operating efficiency with the unique Snyder Columns by Southern Scien tific. Indented float valves make the No-Flood Snyder Columns the ι most efficient you can buy. The in/ i»/ dentations assure optimum vapor/ V liquid contact, for effective separa tion, without column flooding. Valve sticking is prevented and breakage reduced. Greater bubble pattern control reduces sputtering and surging. Southern Scientific offers the improved Kuderna-Danish System at a surprisingly low price. Maxi mum cost efficiency is achieved with the elimination of ground glass on the Macro Snyder Column top joint. Inquire today about the easy to clean, easy to assemble, and easy to replace glass laboratory products from Southern Scien tific. See the difference in your next lab test.

Metropolitan State College, Denver, Colorado CAPILLARY GAS CHROMATOGRAPHY— Techniques and Problem Solving INSTRUCTORS Dr. Stuart P. Cram, Mgr. Research and Development, Varian Associates, Walnut Creek, CA Dr. Milos Novotny, Professor of Chemistry, Indiana University, Bloomington, IN COURSE SYNOPSIS Useful to people doing GC in the chemical, biological, clinical, environmental, occupational health and safety, petroleum, and natural products fields. The course demonstrates practical and advanced techniques of high resolution GC. Lecture materials and demonstrations of the techniques in the field will include discussions of capillary characteristics, recognition of good and bad capillary separations (and how to correct poor results), how to develop capillary GC methods, capillary-GC/MS, micro-GC techniques, a comparison of applications, troubleshooting and preventive maintenance, quantitation, sampling and injection techniques, and factors influencing the separation conditions. Also, laboratory experiments will be offered. All attendees are asked to bring a pocket calculator. The course assumes a working knowledge of GC: either one year of laboratory experience, a BA/BS in chemistry, or completion of a basic GC course. FEE: $ 3 3 0 . Reduced rates/students & retirees

ATOMIC ABSORPTION SPECTROSCOPY— The Latest Word on AAS Applications INSTRUCTORS Dr. Theodore C. Rains, Research Chemist, National Bureau of Standards, Washington, D.C. Dr. Michael S. Epstein, Research Chemist, National Bureau of Standards, Washington, D.C. Dr. S.R. Kiortyohann, Professor of Chemistry, University of Missouri COURSE SYNOPSIS The course is intended for chemists, biochemists, chemical engineers, analysts, and clinicians who are interested in the applications of atomic absorption spectroscopy (AAS) to analyses. The fundamental theory of AAS is presented with a minimum of mathematical treatment. AAS is compared with the complementary techniques of flame emission and inductively coupled plasmas (ICP). The areas of applications discussed include natural and sea water, air pollution, agriculture, glasses, geochemistry, petroleum products, biological tissues and fluids, ferrous and nonferrous metals and alloys.
