MODERN

TITRIMETRY is the topic of

the 20th Annual Summer Symposium on Analytical Chemistry to be held in Claremont, Calif., June 21 to 23. Technical sessions will meet in the Seaver Chemistry Laboratory, Pomona College. Housing and dining facilities will be located at Harvey Mudd College. The program consists of thirteen technical papers. The first day of the symposium is focused on the single topic of specific ion-sensitive electrodes. Concluding this session will be a round table discussion. The remainder of the symposium will include selective coverage from the broad spectrum of recent significant developments in titrimetry. A deliberate effort has been made to provide optimum conditions for audience participation. A ::ull hour is allotted to each speaker and he has been encouraged to leave ample time for discussion. Special events include a mixer at the Joseph B. Piatt Campus Center, Harvey Mudd College, on Tuesday evening and a barbecue at Mt. Baldy, located just north of the campuses, on Wednesday evening. The symposium banquet will be held Thursday evening and the featured speaker will be Dr. Lewis D .

The 20th Annual Summer Symposium on Analytical Chemistry is sponsored by Analytical Chemistry and the ACS Division of Analytical Chemistry

Kaplan of the Jet Propulsion Laboratory of the California Institute of Technology who will speak on "The Atmospheres of the Planets." Dr. Kaplan is internationally known for his work on radiative heat transfer in planetary atmospheres. Special tours are planned for the ladies. One tour will include visits to the Los Angeles County Art Museum and the Farmers Market. The other tour will be to the Huntington Library, Art Gallery, and Botanical Gardens followed by lunch and shopping in Pasadena. The tours will be scheduled according to demand at the time of registration and will run concurrently with the meetings during the day. Claremont, California, can be reached by air via Ontario International Airport (six miles away) or by helicopter from the Los Angeles International Airport to Pomona (four miles away). Limousine service is also available from the Los Angeles International Airport to Montclair (four miles away). Transcontinental train connections can be made to Pomona. Room and board is available both for participants and their families. Rooms will be available on Tuesday

afternoon, June 20. Total charge for room, Tuesday through Thursday nights, and breakfast and lunch, Wednesday through Friday, will be $18.00 per person in a double room, $22.50 per person in a single room. The rate for children under 11 is $12.00. The meal package is available separately for $9.00 per person. Rooms may also be reserved for the Friday night following the symposium at $3.00 per person in a double room and $4.50 per person in a single room. Information on motels in the vicinity of Claremont is available from the local arrangements committee. Please fill out the registration form and return it before June 1, 1967, to reserve accommodations and to receive appropriate information. The Program Chairman for the symposium is Dr. Joseph Jordan, Department of Chemistry, Pennsylvania State University, University Park, Pennsylvania. Co-chairmen in charge of local arrangements are Dr. Alvin L. Beilby, Department of Chemistry, Pomona College, and Dr. Roy A. Whiteker, Department of Chemistry, Harvey Mudd College, Claremont, California.

New 600 keV electron accelerator for high-speed phenomena FEBETRON 7 0 6 T h e o s c i l l o g r a p h above shows the transmitted current in the external electron beam of a Febetron 706 accelerator. The amplitude is 7000 amperes, the pulse length is 3 nanoseconds at the half current points. The peak beam power is more than 3000 m e g a w a t t s — e n o u g h to activate a lot of mechanisms in a hurry! What can it be used for? For one thing, the study of fast decay processes—shortlived chemical radicals, electron induced fluorescence, electronic radiation effects, etc. And the electron range is ideal for both gas radiolysis and for cellular biological specimens where dose rate effects may be studied. As a diagnostic tool it can take highs p e e d p h o t o g r a p h s — b o t h X-ray and electron beam s h a d o w g r a p h s with " s t o p m o t i o n " clarity for a wide range of object thicknesses and densities. And it may be useful as a dynamic electron beam probe for gas densities in shock waves. Design is similar to that of other Fexitron and Febetron instruments w h i c h are available in a complete line of time-tested equipment ranging from 50 kV to 2 million volt systems. Fexitron field emission X-ray devices have enjoyed widespread customer acceptance for more than eight years—the Febetron field emission beta ray devices for more than three years. At $14,970 the Febetron 706 provides a precision instrument for quantitative research at relatively low cost. Energy is r e p r o d u c i b l e to -*; 5 % rms. Time of fire is c o n t r o l l e d to ±- 50 ns (standard) or ± 7 ns (special). Several beam parameters are adjustable. A high signal-tonoise ratio is provided by coaxial con-

It isn't easy to trap a GC fraction. It is even harder to get a fraction into an IR cell. But, from a qualitative standpoint, the results are well worth the effort! A good, practical solution to the problem is the Wilks Scien tific MIR-15 GC-IR Analyzer. With it, a one half microliter sample in jected into the chromatograph can be trapped and a spectrum recorded with nearly full-scale deflection. Much smaller samples can be caught and analyzed on spectrophotometers equipped with scale expansion. The MIR-15 consists of a hand-held thermo-electric cooler on which is mounted a capillary internal reflection cell. The fraction is trapped di rectly in the cell which is then moved to the spectrophotometer for analysis. Since there are no sample transfer steps, the device is efficient and simple to use with practically no chance of sample contamination. The MIR-15 GC-IR Analyzer can be adapted to any chromatograph and infrared spectrophotometer. Write for details.

but you save $215· When we got tired of the simple, functional lines of our titrator for Karl Fischer moistures, we designed a new, streamlined one. Did every thing our homely one did, just as fast and accurate too, When we checked and found the new titrator would cost almost $600-to produce, w e said "Phooey!" We think it's silly to charge a lot more money for a new model that doesn't do anything more. We're glad you agree—for you bought more WACO titrators this year than in any previous year. While it still looks the same, our titrator shown above now features ball joint Pyrex glassware that won't drip, a unique drain flask, WACO magnetic stirrer, and many other exclusive advantages. But you still pay just $435. instead of $650.

A new international periodical, Jour nal of Molecular Structure, is scheduled to begin publication on a bimonthly basis. The main objects of the new journal, which is to serve chemists, physical chemists, and chemical physi cists, are to overcome the fragmenta tion on structural work between numer ous publications and to speed up pub lication. Timely reviews of value both to specialists and to the general reader will be included in the journal. In ad dition, main contributions delivered at international conferences will be pub lished. Editors of the new journal are : Pro fessor W. J. Orville-Thomas, Royal College of Advanced Technology, Salford, Great Britain, and Professor J. Lecomte, Laboratoire des Recherches Physiques de la Faculté des Sciences de Paris, 9, quai St. Bernard, Paris 5e, France.
