over α w i d e temperature r a n g e NEW, COMPACT LOENCO MODEL 15 gas chromatograph provides the widest range of analyses at very modest cost. Instru ments may be operated singly or con nected in series operating at different temperature levels for best combination of separation and speed. A combination of features most satisfactory for your needs will be suggested.
model Τ 5 features: • Measures 13V4X12". Wt. 40 lbs. • Temperature range—from Ambient to 300 degrees C. At small extra cost to 350 degrees C. • High sensitivity, shielded element detector. Choice of 2 element thermistor detector, or 2 or 4 ele ment filament detector. • Bubble meter assembly. • Precise electronic temperature control, propor tional type. • Reproducible volume gas sample value. (May also be used for trap-out, pre-separator or pre-concentration.) • Column reverse valve. • Preparation scale column for separating large samples. • Hot sample outlet fitting for sample collection. • Ample oven space for long columns, easy access to column connections. • Two column series system.

For the Xew York meeting, symposia have been organized on nuclear mag netic resonance and electron paramag netic resonance, x-ray absorption and emission methods, infrared methods of chemical analysis, and recent advances in analytical chemistry. The infrared symposium is cosponsored with the Di vision of Physical Chemistry, while the symposium on recent advances is cosponsored with the Division of Chemi cal Education. The St. Louis meeting will be con ducted over a two-week period on a split basis, as was the meeting last spring in Cleveland. Symposia plans here call tentatively for presentation on the. subjects of high polymers and functional groups. In addition, the ACS petroleum division has suggested cosponsorship of a symposium on gas chromatography. Dr. H. A. Liebhafsky, division chair man, in his spring report to the analyti cal chemistry division, adds that the split meeting concept seems to preclude a projected joint symposium with the Division of Agricultural and Food Chemistrj7 on new analytical techniques for food analysis.
Pittsburgh Diffraction Conference The annual Pittsburgh Diffraction Conference will be held at Mellon Insti tute, Pittsburgh, Pa., Nov. 9 to 11. Sessions will be devoted to metals and alloys, instrumentation, structures, polymers and fibers, refractories, elec tron probe and electron diffraction. The evening meeting will be addressed by Prof. I. Fankuchen, Polytechnic In stitute of Brooklyn. Further informa tion can be obtained from L. F. Vassamillet, Mellon Institute, 440 Fifth Ave., Pittsburgh 13, Pa.
Microchemical Techniques Symposium Planned An International Symposium on Mi crochemical Techniques, sponsored by the International Union of Pure and Applied Chemistry, will be held at Princeton, X. J., Aug. 13 to 18, 1961. The Metropolitan Microchemical Soci ety will organize the 6-day meeting. Individuals interested in presenting papers describing original work on mi crochemical techniques and their ap plications should submit titles and ab stracts as soon as possible. These should be sent to Howard J. Francis, Jr., Pennsalt Chemicals Corp., Box 4388, Chestnut Hill Post Office, Phila delphia 18, Pa.
