HE 139TH NATIONAL ACS MEETING is a split meeting, as

T was the case at Cleveland

in 1960. The Division of Analytical Chemistry, together with 10 other Divisions (set forth in box) will meet during the period Wednesday, March 22 through Saturday noon, March 25. Nine other divisions will meet from Monday, March 27, through Thursday, March 30. The complete program appears in the February 13 issue of Chemical and Engineering News. Technical sessions will all be held in the Kiel Auditorium. Registration facilities will be located in the Kiel Auditorium, the Sheraton-Jefferson, and Statler-Hilton Hotels. The Kardex file of registrants will be at the Kiel Auditorium. The Employment Clearing House will also operate in the Kiel Auditorium from March 21 through March 30. Analytical Division Program. Symposia honoring recipi ents of the Fisher Award in Analytical Chemistry, the Sar gent Award in Chemical Instrumentation, and the Labline Award in Chromatography and Electrophoresis will high light the diversified program scheduled for the Division of Analytical Chemistry. A total of 15 half-day sessions are scheduled. The Wednes day morning sessions will be devoted to the Fisher Award Symposium honoring Dr. Herbert A. Laitinen, University of Illinois. The Wednesday afternoon session will be a sym posium honoring the Sargent Award winner Dr. Marcel J. E. Golay of the Perkin-Elmer Corp. There will be a half-day joint symposium on Thursday morning with the Division of Agricultural and Food Chem istry on Physico-Chemical Methods for Quality Evaluation. Another joint symposium, with the Division of Petroleum Chemistry, will be held on Thursday morning and afternoon on the subject of Gas Chromatography. A Symposium on the Analysis of High Polymers is sched uled for Thursday afternoon and Friday morning. A one-day symposium, to be held on Friday, will deal with Selective Separations by Differential Migration Meth ods. This is in honor of Dr. Η. Η. Strain, recipient of the Labline Award in Chromatography and Electrophoresis. A three-session symposium on Analysis via Functional Groups will start on Friday morning and run through Satur day noon. General Sessions are scheduled for Thursday morning, Friday afternoon, and Saturday morning. The Divisional Dinner will feature as speaker Edward M. Flesh, McDonnell Aircraft Corp. His topic will be "The Challenge of Space." This affair will be held at 6:30 p.m. Thursday, March 23, at the Statler-Hilton Hotel, Missouri Room. 52 A

• Column oven accommodates a variety of high efficiency columns. • Columns may be quickly and easily changed. • Separately heated injection block for " f l a s h " vaporization of sample from room temperature to 350° C. • Convenient micrometrically adjustable sample splitter divides the sample into reproducible ratios. • Column oven may be* maintained within 0.5° C with boost control for rapid heating or temperature programming to 250° C. • Detector may be set for any temperature range from room to 250° C. • It is available with a choice of interchangeable detectors: micro argon diode and triode detectors with choice of Ra 226, Sr 90 or tritium emitters; flame; even the experimental electron capture detectors are available for interchangeable use in the detector mount. • This latest Jarrell-Ash contribution to the field of gas chromatography is now priced for even the most modest laboratory budget. All of the Jarrell-Ash detectors, ovens, injection blocks, columns, sample splitters etc., are available as separate components for those who may wish to modify or modernize existing equipment or assemble their own chromatographs. For those engaged in the study of lipid metabolism or fatty acid chemistry, remember that our W. G. Pye Argon Chromatograph is the standard instrument for this work.

VDF MICRO TORQUE BALANCES VDF Micro Torque Balances are widely used in science and industry for repetitive weighings of small samples. These balances are extremely fast, yet accurate and simple to oper ate. Service requirements are negligible due to the absence of moving parts, bearings, springs and other complicated mechanisms. Select from 14 different models,- all at surpris ingly low, economy prices. SPECIAL FEATURES: • No bearings—no friction • Combined torsion/suspension wire • No delay in reading, oscillation stops instantly • Direct reading, no reading errors • No fatigue, dial at eye level is adjustable • No parallax—special straight view pointer • Considerable overload tolerance For descriptive literature write for Bulletin 66
