21st Mid-America Symposium on Spectroscopy Chicago, Ill., June 2 to 5, 1970

T P H E CHICAGO SECTION of the So-ciety for Applied Spectroscopy, in

cooperation with other Mid-Western Sections of the SAS and the Chicago Gas Chromatography Discussion Group, will sponsor the 21st Mid-America Sym­posium on Spectroscopy. All facets of the meeting will be conducted at the Sheraton-Chicago Hotel in Chicago, 111., June 2 through June 5, 1970.

The technical program for the 21st Mid-America Symposium on Spectros­copy will feature over 190 papers in all areas of spectroscopy. These include absorption, emission, mass, nmr, esr, X-ray, nuclear, electron, and flame atomic absorption spectroscopy. Of special interest will be the symposia on Fourier transform spectroscopy, 220 MHz nmr, and nmr spectrometry train­ing. Papers will also be concerned with air and water pollution analyses, com­puter applications, and gas chromatog­raphy methods. Analytical spectros­copy methods dealing with polymers and elastomerio materials as applied to biomedical technologies will be the sub­jects of two special sessions.

Spectroscopic and gas chromato­graphic instruments and related equip­ment and supplies will be on display. Exhibitor seminars will provide the op­portunity for group demonstration of instruments.

In conjunction with the Symposium, the ACS will conduct a Short Course on June 5 and 6. The subject is "The Small Computer in the Chemical Lab­oratory," and will be given by R. E. Dessy and David G. Larson of Virginia Polytechnic Institute.

For additional symposium informa­tion, contact W. A. Loseke, I IT Re­search Institute, 10 W. 35 St., Chicago, 111. 60616.

Advance registration forms and hous­ing information for the Short Course may be obtained from the Education Office, ACS, 1155 16th Street, N.W., Washington, D.C. 20036.

The detailed technical program given below is arranged by topic and then by date rather than chronologically which is the usual custom in ANALYTICAL CHEMISTRY.

Cary, continued. No spectrophotometer, including ours, is complete without good absorption cells.

So we offer a complete line of rectangular and cylindrical cells.

Like others, our cells cover the entire ultraviolet, visible and near-infrared

range. Unlike the others, we use only two types of glass. Suprasil II provides

opt imum transmission in the visible and UV, while Infrasil outdoes itself in the near-infrared.

As a result, you need fewer cells. You save money and do better work, regardless

of whose spectrophotometer you're using. For li terature and a price list, write Cary

Scanning Electron Microscopy The Electron Microscopy and Analy­

sis Group of The Institute of Physics and The Physical Society, in association with the Royal Microscopical Society, is arranging a conference on scanning electron microscopy in materials sci­ence to be held at the University of Newcastle-upon-Tyne from July 7 to 9, 1970. Main emphasis of the meeting will be new techniques of scanning elec­tron microscopy rather than routine ap­plication. Chief topics will be instru­mentation and electron physics [high resolution, reflection, and transmission of scanning electron microscopy (SEM); high-voltage SEM; high-speed scanning systems; compositional ana­lyzers; special specimen stages; stro­boscopy; contour mapping; computa­tion of images] and applications and in­terpretations (fibers and polymers, metallography, mineralogy, solid-state devices, voltage and magnetic contrast, beam-induced effects, recombination ra­diation, and diffraction effects).

An exhibition and demonstration of commercial scanning electron micro­scopes and ancillary equipment will also be part of this meeting.

Further details and application forms are available from the Meetings Officer, The Institute of Physics and The Physi­cal Society, 47 Belgrave Square, Lon­don SW1, England.
