serves

many operations simply by changing the inexpensive vacuum shroud interface. These refrigerators operate by the Joule-Thomson expansion of economical, convenient cylinder gas, eliminating the need for liquid helium. Gives precise temperature control from 3.6° K to 300° K by simply varying gas pressure. Cryo-Tip refrigerators are now used for low-temperature experiments in UV, IR, visible and nuclear spectroscopy with interfaces for many makes of spectrometers. Other uses include x-ray diffraction, Hall effects, field-ion microscopy, semiconductor studies, ESR, EPR, NMR and cooling of lasers and low-noise receivers. Available for open- or closed-cycle —

Symposium on Physicochemical Bases for Chromatography

The Division of Industrial and Engiits 37th neering Chemistry announces Annual Chemical Engineering Symposium, which will be held Dec. 14 and 15, 1970, at Tulane University, New Orleans, La. The subject is “Recent Advances in Establishing the Physicochemical Bases for Chromatography.” Areas to be covered include gas-liquid, gas-solid, and liquid-liquid chromatography. Quantification of these areas both in terms of new theories and experiments will be discussed. Primary

interest will be in principles rather than in specific separations. The meeting is being designed to stimulate analytical chemists, physical chemists, and chemical engineers who arc interested in recent advances in understanding the principles underlying chromatographic separations. Papers are being solicited: those interested should submit an abstract before June 1 to the symposium chairman, Riki Kobayashi, Dept, of Chemical Engineering, William Marsh Rice University, Houston, Tex. 77001. 713-5284141, ext 485
