155th National ACS Meeting, San Francisco March 31 to April 5, 1968 Monday Morning, Apr. 1

ANALYTICAL DIVISION of the American Chemical So­ T HE ciety has planned a full week of stimulating and varied

technical sessions for the 155th National American Chemical Society Meeting in San Francisco. Nearly 240 papers will be given m special symposia and general sessions sponsored by the Analytical Division alone or in conjunction with other divisions. Joint symposia will be held with the Polymer Division, the Division of Fluorine Chemistry (the whole of its program consists of sessions on instrumental and chemi­ cal analysis of fluorine-containing molecules), and the Di­ vision of Water, Air, and Waste Chemistry. Included in the program will be special symposia honoring the ACS award winners in analytical chemistry; chromatography and elec­ trophoresis; and instrumentation. Analytical Chemistry Division sessions will all be held at the Civic Auditorium with the exception of the joint sessions with the Division of Water, Air, and Waste Chemistry which will meet at the Fairmont Hotel, April 3 and 4. This special symposium, "Instrumental and Automated Methods for Chemical Analysis for Water Pollution Control," has par­ ticular relevance to our national problems concerned with water quality and should be of interest to many chemists. Titles of the sessions are : Water Quality Parameters ; Water Quality Monitoring Systems; In Situ Analysis; and Auto­ mated Analytical Techniques. Other special symposia of particular interest will be held on analytical calorimetry (joint with Division of Polymer Chemistry), microwave spectroscopy, and physical chemical applications of gas chromatography. L. G. Longsworth, winner of the ACS Award in Chroma­ tography and Electrophoresis (sponsored by Lab-Line In­ struments, Inc.) will speak at the Monday afternoon session of the symposium on electrophoresis. He will discuss optical methods in electrophoresis, diffusion, and sedimentation. The symposium on developments in metallurgical analysis, which honors J. R. Churchill, winner of the ACS Award in Chemical Instrumentation (sponsored by Ε. Η. Sargent & Co.) will also be held Monday. J. R. Churchill will address the Monday afternoon session on metallurgical analysis— wet and dry. L. B. Rogers, winner of the ACS Award in Analytical Chemistry (sponsored by the Fisher Scientific Co.) will be honored by a special symposium Wednesday, April 3. Selectivity and resolution in gas-solid chroma­ tography is the subject of his address, which will be pre­ sented at the Wednesday afternoon session. The California Section, ACS, and the American Chemical Society are sponsoring the chemical exposition which will be held April 2 to 4, in Brooks Hall, Civic Auditorium. Chemicals, equipment, instruments, publications, and ser­ vices will be displayed in 185 booths. The detailed program of the Analytical Division sessions and special symposia is given below. Chairman of the Division is E. C. Dunlop, Experimental Station, E. L du Pont de Nemours, Co., Wilmington, Del. 19898. James C. White, Oak Ridge National Laboratory, Oak Ridge, Tenn. is Secretary-Treasurer. Chairman-Elect is Fred MoLafferty of Purdue University. Chem. Eng.

TRI-VALUABLE MODERN METHODS OF CHEMICAL ANALYSIS By ROBERT L. PECSOK, University of California at Los Angeles; and L. D O N A L D SHIELDS, California State College at Fullerton

GAS CHROMATOGRAPHY

A thorough and detailed explanation of the methods used by modern chemists to measure and to determine composition and structure. Applications to organic chemistry and to bio­ chemistry are emphasized, together with basic p r i n c i p l e s of m o d e r n chemical analysis, the types of information obtained, and the inter­ pretations of the results. Among the analytical methods considered are chromatography, spectrophotometry, nuclear magnetic resonance, mass spectrometry, electro­ chemistry, kinetics, and acid-base chemistry. Intended for students who have already com­ pleted course work in introductory chemistry. 1968 In press

Offering a new approach to analytical methods of organic and biochemistry, this laboratory m a n u a l p r e s e n t s m a t e r i a l p e r t i n e n t to that course and also to other courses which the stu­ dent may be taking. Applications are immediate, and the subject ceases to be merely an exercise in patience, perseverance, and strict attention to detail. Instead, this manual proceeds from a study of phase transition to the various forms of chromatographic separations, to a group of ex­ periments in modern spectroscopy (including nmr and mass spectrometry), to equilibrium studies in aqueous and non-aqueous solvents ( of which many pertain to the study of kinetics ). Throughout, the authors emphasize the deter­ mination of molecular structure by modern ana­ lytical methods and, conversely, the effect on molecular structure of chemical reactions.

New Double Beam UV Monitor U V I S C A N No other U V Monitor offers all t h e s e a d v a n t a g e s . . . • Optical bench, amplifier and power sup­ ply in a single housing—only 7 lbs. · Sensitivity better than .01 O.D. · Linear or logarithmic output · Interchangeable in­ terference filters f o r 240, 260 or 280 mu range · Solid state, modular construction

Uviscan III combines high sensitivity with a unique double flow cell design. Because of its light weight, it can be mounted directly on a fraction collector. It identifies compounds by comparing the intensity of light transmitted through an absorbing substance in one of its flow cells with that of a buffer solution flowing through a reference cell. In the logarithmic mode, highly absorbent compounds remain on scale without a loss of sensitivity for low absorbent compounds. With the Uviscan III it is possible to monitor such compounds as nucleatides, proteins, hormones, steroids, enzymes, vitamins and many others. For further information, request Technical Bulletin AC3-5060.

Conference on Modern Trends in Activation Analysis The National Bureau of Standards will host the 1968 International Con­ ference on Modern Trends in Activa­ tion Analysis, October 7 to 11. The planned program will be useful both to those without experience in activation analysis and those who have studied specialized areas in detail. Both in­ vited and contributed original papers will be included. The titles of invited lectures are: Practical applications of activation anal­ ysis Nuclear reactions and principles used in activation analysis Standardization of activation analysis Radiochemistry in activation analysis Radiation detectors in activation analy­ sis Computation and handling of data in activation analysis

In addition to technical sessions, there will be a social program and op­ portunity for informal contacts among the participants and a ladies' program. The proceedings will be published by the National Bureau of Standards and mailed each registrant as soon as pos­ sible after the meeting. James R. DeVoe of the National Bu­ reau of Standards heads an organizing committee composed of members from the U. S., England, and Europe. Further information on this meet­ ing may be obtained from the Analyti­ cal Chemistry Division, Institute for Materials Research, National Bureau of Standards, Washington, D. C. 20234.

Conference on Competing Spectrochemical Techniques A conference on Competing Spec­ trochemical Techniques will be held at The University of Keele from July 10 to 12, 1968. The meeting will high­ light areas of overlap between spec­ trochemical techniques and compare and contrast alternative techniques. Examples are optical emission vs. x-ray fluorescence spectrometry for the de­ termination of major constituents in common metals, and neutron activa­ tion analysis vs. mass spectrometry for the determination of trace impurities in high purity materials. Further information on this meet­ ing is available from the Meetings Officer, The Institute of Physics and The Physical Society, 47 Belgrave Square, London, S. W. 1, England. 96 A

SPECTROSCOPY

Cryo-Tip Refrigerators: inexpensive solutions to difficult cryogenic interfaces. • Temperatures down to 3.6° Κ • Temperature control to ± 0.1° Κ • Uses gaseous, not liquid, h e l i u m . • Wide variety of interfaces available. A single Cryo-Tip* Refrigerator serves many operations simply by changing the inexpensive v a c u u m shroud interface. These refrigerators operate by the Joule-Thomson expansion of economi­ cal, convenient cylinder gas, eliminat­ ing the need for liquid h e l i u m . Gives precise temperature control from 3.6° Κ to 3 0 0 ° Κ by simply varying gas pressure. Cryo-Tip refrigerators are now used f o r low-temperature experiments in UV, IR, visible and nuclear spectroscopy — w i t h i n t e r f a c e s f o r m a n y m a k e s of spectrometers. Other uses include x-ray d i f f r a c t i o n , Hall effects, field-ion mi­ croscopy, s e m i c o n d u c t o r studies, ESR, EPR, NMR and cooling of lasers and low-noise receivers. A v a i l a b l e f o r o p e n - or c l o s e d - c y c l e " p l u g - i n " operation.
