OOLLJTION chromatography will be ^ the broad area of analytical chemistry under discussion at the 14th annual Summer Symposium at Case Institute of Technology, June 21 to 23. Sponsored as usual by the American Chemical Society's Division of Analytical Chemistry and the ACS publication,

ANALYTICAL

CHEMISTRY,

the

meeting continues a long-standing tradition as to locale. The entire series has been held on university and college campuses in order to ensure an atmosphere conducive to -cholarly discussion. In all, 14 technical papers are scheduled for presentation by authors representing a variety of educational, governmental, and industrial organizations. Individual papers deal with broadly applicable techniques or with methods of studying classes of—rather than individual—substances.

The banquet for the meeting is scheduled for Thursday, June 22. The cost for this has not been definitely set, but tentatively is anticipated to be about $4.50. The speaker will be Dr. A. L. Jones, The Standard Oil Co., who has chosen as his topic, Radio-Satellite Tracking. Dinner tickets can be purchased at the time of registration. Dr. Jones, who is supervisor in charge of basic research at Standard Oil, and his associates constructed a tracking station prior to the launching of the first United States satellite. This was done under a company-supported extracurricular program, and the station has been in continuous operation since its construction. Tape recordings of signals received from various satellites will be a feature of the talk. Dr. Robert Thomas, director of re-

search administration, Case Institute of Technology, will be the toastmaster at the dinner. A tour of the Research Center, The Standard Oil Co., has been arranged for Friday afternoon, June 23. Depending upon an expression of the desires of those persons attending the meeting at the time of registration, plans are being made to purchase a block of tickets for an evening baseball game between the Cleveland Indians and the Detroit Tigers. This is tentatively scheduled for Friday night, June 23. All recreational facilities of Case Institute are available for use by symposium participants. Case Institute of Technology is only a few minutes travel by rapid transit from downtown Cleveland. Housing arrangements include the availability of rooms in the Case dormitory and at the Tudor Arms Hotel. Rooms in the dormitory are priced at $6.75 to $15.75 for periods of one to four days, respectively, single; and they are $4.50 to $10.50 per person double, also for periods of one to four days. The Tudor Arms Hotel, operated jointly by Case Institute and Western Reserve University, is located adjacent to the campus. Rates here range from $8 to $10 per day single, and from $14 to $16 per day double, twin beds. All technical papers will be presented in Strosacker Auditorium of the Institute. Dr. Donald H. Wilkins, General Electric Research Laboratory, is program chairman of the symposium. Dr. Karl H. Roberts, The McGean Chemical Co., is local chairman. To allow flexibility in presenting and discussing papers, no specific times have been set for presentation of individual papers. The morning sessions will start at 9:00 A.M. (except first day when starting time is 9:30 A.M.). The afternoon sessions will start at 2:00 P.M. VOL.

FOR LESS THAN $ 2 0 , 0 0 0 . . . With the development of the Jarrell-Ash Compact Atomcounter, it is possible for any analytical laboratory to realize substantial savings in the cost of analysis with a minimum capital investment. The Compact Atomcounter is, by far, the lowest priced direct-reading polychromator on the a.arkct today . . . yet its analytical accuracy is equal to that of the moot expensive models. Any control laboratory performing as few as ten routine analyses per day can pay for this instrument in less than two years, just with the money saved by replacing wet chemistry analysis method*. The Compact Atcncounter is designed to n-.pet the requirements of laborator-.es concerned with the daily analyses of material? such as low inciting point alloys, most ferrous metals, slap.s, ores, leaves and soil, minerals, and oils. In less than two minutes .the Compact Atpjn£Ount.e_r can analyze a sample for a_s many its twenty^two elements. Through its electronic readout circuitry, the instrjxer.t provides- a redd1.r.f, for each element on η four dip.it scaler. The Compact Atomcounter is simple in operation. With a few hours instruction, one laboratory technician is capable of analyzing up to 150 camples per day for 10 or more elements.

The 1961 Eastern Analytical Sym posium will be held at New York City's Statler Hilton Hotel from Nov. 15 to 17. Held annually and concurrent with an instrument exhibit, the meeting is sponsored jointly by the Metropolitan Microchemical Society and local sec tions of the American Chemical So ciety and the Society for Applied Spectroscopy. Dr. Saul Gordon, Fairleigh Dickin son University, has been named gen eral chairman of the meeting, while Dr. Eugene Rosenbaum, Drexel Institute of Technology, is program chairman. In quiries regarding space for the con current instrument exhibit should be addressed to Norman Gardner, 73 Ethel St., Metuchen, N. J.

Brooklyn Polytech Schedules Intensive Summer Courses A scries of intensive one- and twoweek courses in the use of specialized tools in chemistry and physics will be offered this summer by the Polytechnic Institute of Brooklyn. A two-week course in Industrial Application of X-Ray Diffraction will be given from May 29 to June 9. This will cover the equivalent of a sixcredit lecture and laboratory graduate course. Studies will be made at high and low temperatures, using either photographic or direct recording devices. Advanced techniques can be included by special prior arrangement. A one-week course in Applied Infrared Spectroscopy, from June 5 to 9, will deal with applying IR techniques to problems of qualitative identification. The course will be conducted daily from 9:30 to 8 P.M. Laboratory sessions will emphasize manipulations and interpretation, and will include demonstrations of commercial instruments. Xo previous experience will be assumed, but here again advanced work can be specially arranged. Polarography and Related Techniques will be the subject of a third course, to be given from June 5 to 9. It will include a summary of theory of polarography and other voltammetric methods that are closely related, as well as an introduction to the use of modern electrolytic and eoulometric techniques in research and analysis. Laboratory sessions will feature application of apparatus. Previous experience with polarography is not required. Inquiries regarding these courses should be addressed to Airs.

Minnesota Announces Summer IR Spectroscopy Courses The University of Minnesota is offering its 3rd annual series of courses

in infrared spectroscopy. The first, Techniques of Infrared Spectroscopy, will run from Aug. 1 through Aug. 5, and it will be followed by Chemical Interpretation of Infrared Spectra, from Aug. 7 through Aug. 11. Although related, the courses operate independently and participants may register for either or both. Prospective students should have basic training in chemistry and physics, but no experience in spectroscopy is assumed. The techniques course will include lectures on basic optics and instrument theory, instrument design, sample preparation, and laboratory techniques. Laboratory work will provide experience in those techniques. The interpretation course lectures will systematically cover the group frequencies useful m chemical diagnosis and structure determination. They will also deal with factors giving rise to these group frequencies and their variations, as well as with the practical use of infrared in day-to-day chemical work. Practice on interpretation of typical spectra unknowns will be provided. Further information can be obtained from the Director, Center for Continuation Study, University of Minnesota, Minneapolis 14, Minn.
