Program Listed for Eighth Anachem Conference in Detroit T h e program of technical papers to be presented at. the 8th Detroit Anachem Conference, sponsored b y the Association of Analytical Chemists, has been announced. T h e meeting is to be held at the McGregor Memorial Conference Center of Wayne State University in Detroit, Oct. 24 to 26. Sessions will be conducted on general analytical methods, gas chromatography, solvent extraction, polarography, emission and absorption spectroscopy, clinical chemistry, and x-ray fluorescence. In addition, there will be a symposium on activation analysis, having the goal of denning the status of neutron activation analysis in terms that are meaningful to t h e practicing analytical chemist. T h e p r i m a r y theme of this symposium is slanted toward possible production uses, with less emphasis on pure research applications. Other features on the general program include an award session in honor of H a r r y A. Bright, National Bureau of Standards, and a conference address by Dr. E d w a r d Wichers, National Bureau of Standards Associate Director for Chemistry. D r . Wichers will speak at the conference banquet on Tuesday evening, his subject being preparation and evaluation of pure substance standards. T h e award session, to be held on Tuesday afternoon, will honor D r . Bright for outstanding achievement in analytical chemistry. An analytical equipment exhibit will feature the products of about 30 manufacturers. Registration fees for the conference are S4, or $1 for students. T h e cost for luncheons on each of the three days is S3, while t h a t for the banquet on Tuesday evening is $5. Registration forms can be obtained from D r . D . A.

A. M. Wilson, Wayne State University, chairman LHERE are some fields of industry, some professions, where more than ordinary T„ care is required. Food is one, medicine another, chemical research a third. Here purity in its truest sense must be enveloped with meticulous care every step of the way. Relatively minor elements of equipment often play a vital part. For example, if the tubing used to transport liquid food should be attacked by one of the food chemicals trouble could be serious; a life could be endangered if the wrong tubing were used to convey blood or blood plasma; a research project could fail if contaminants leached out to spoil a solution. This is why those whose job it is to safeguard purity specify Tygon Tubing for critical tasks. This flexible, plastic tubing, crystal clear, flexible as a piece of string, tough as leather, resistant to acids and alkalies, offers a combination of properties found in no other material. And like metal alloys, basic properties of this unique "flexible glass" plastic tubing can be varied to meet a wide range of special requirements. Thus, Tygon Tubing is made in many standard formulations and in innumerable special ones. That is why those whose job it is to safeguard purity specify the specific formu lation of Tygon Tubing designed to fit their exact needs . . . for they know, as do we, that no single formulation can do all things well. PLASTICS & SYNTHETICS DIVISION Tygon plastic Tubing is made in many formulations, each designed for a spe cific usage . . . and in over 66 sizes, from 1/16" to 4" I.D. Write for Bulletin T-100.

ent firm of CEC, and CEC's Analytical and Control Division. Selected staff members of neighboring academic institutions have been in vited to the seminars, which are pri marily for technical staffs of the spon soring groups. Chief purposes of the talks are to acquaint those attending with current trends in undergraduate and graduate training in analytical chemistry, and with the increasing emphasis on instru ment techniques as both teaching aids and research tools.
Microscopy Course Offered at Cornell Facilities are available for a few more students in the 3-wcck course in chemi cal microscopy to be given at Cornell University starting July 11, according to Prof. C. W. Mason (ANAL. C H E M ,
March, page 60A). Emphasis in the course will be on principles and basic methods rather than on routine tech niques, with instruction at the upperclass or graduate level. The course fee, payable at registration, is $250. Regis tration deadline is July 5. Dr. Mason says that housing is available in Uni versity dormitories, if reserved in ad vance. Correspondence should be ad dressed to Dr. C. W. Mason, School of Chemical Engineering, Olin Hall, Ithaca, Ν. Υ.
ISA Fall Meeting Features 50 Technical Sessions More than 50 technical sessions are to be offered at the Instrument So ciety of America's Fall Instrument-Au tomation Conference and Exhibit, to gether with its 15th annual meeting. The event is being held at the New York City Coliseum, Sept. 26 to 30. Nearly 400 leading instrument man ufacturers will display and demonstrate the latest developments in scientific equipment. A number of the exhibits will be presented by the various branches of the armed services, and the National Aeronautics and Space Ad ministration will offer an exhibit deal ing with space exploration and with satellites. Among the sessions planned are those covering chemical and petroleum in strumentation, metals and ceramics in strumentation, nuclear instrumenta tion, sample handling, laboratory anal ysis instrumentation, and standards measurements. Details are available from ISA, 313 Sixth Ave., Pittsburgh 22, Pa.
