1982 Gordon Research Conferences Each year the Gordon Research Conferences aim to extend the frontiers of science by fostering a free and informal exchange of ideas among persons actively involved in research in particular fields of study. At each conference, meetings are held in the morning and evening, Monday through Friday, with the exception of Friday evening. The afternoons are available for recreation, reading, or participation in study or discussion groups. This year, there are four conferences of particular interest to the analytical chemistry community: analytical chemistry; electron spectroscopy; separation and purification; and vibrational spectroscopy. Technical schedules for these conferences follow. Other conferences of interest to analytical chemists include: bioelectrochemistry; environmental sciences (water); immobilized species; lasers in medicine and biology; magnetic resonance in biology and medicine; molecular electronic spectroscopy; toxicology and safety evaluations; and visible/ UV multiphoton ionization and dissociation. Individuals interested in attending one of the conferences must submit an application on the standard application form issued by the Gordon Research Conferences. This procedure is important because specific information is required so that a fair decision on the application may be made. Attendence at each conference is limited to approximately 100 conferees. A registration card will be mailed to those selected. Conference fees, which cover registration, room (except single room or room with private bath), and meals, are as follows: conferee (double occupancy), $230; nonresident conferee (meals, no room), $190; guest (room, meals), $170. Requests for application forms or additional information should be directed to: Alexander M. Cruickshank, Gordon Research Conferences, Pastore Chemical Laboratory, University of Rhode Island, Kingston, R.I. 02881, 401-783-4011 or -3372. From June 14 to Aug. 27, Cruickshank may be

Scientists at the Calgon Corporation in Pittsburgh, Pa., are using photon correlation spectroscopy to measure the continuous size distribution of water-soluble polymer molecules and other particulate dispersions in liquid samples. C.Y. Cha of Calgon (right) uses a precision laser probe to continuously measure the speed of the Brownian movement of polydisperse polymers in solution. The data is analyzed by a largescale computer on a real-time basis to determine the continuous weight and size distribution of the polymer molecules, present in liquid samples as small as 5 mL. Each measurement requires less than one-thousandth of a second, permitting a large number of measurements to be made during the course of an experiment. Cha's research also opens the door to more accurate studies of re-

actions involving emulsions, flocculants, and extremely small suspended particles. By monitoring molecular size distribution at all times during a reaction, Calgon scientists hope to learn how size affects water treatment product performance under various conditions.

Introducing The Abuse Proof GLT Column The new GLT column is so strong that we ran over it with a light truck, dropped it onto a concrete floor and still got sharp, symmetrical peaks with no indication of metal catalyzed decomposition. Not only is the GLT strong but SGE's consistent column packing techniques and rigorous quality control procedures insure the highest degree of column to column reproducibility. No other column on the market today offers the strength of stainless steel and the inertness of Head Office & International Sales: Scientific Glass Engineering Pty.

Robotics Center Established at University of Rhode Island The federal government and more than 30 industrial firms have joined resources to establish a center for robotics at the University of Rhode Island (URI). The center is an outgrowth of a robotics project supported by the National Science Foundation and is intended to be an experiment in university-industry cooperation. Research at the new center will be aimed at industrial applications for robotics systems. A four-year NSF grant to URI of $700,400 will be matched in the first year alone by contributions totaling $750,000 from the firms now involved in the project. The center, called the University/Industry Center for Robotics, will be headed by John Birk and Robert B. Kelley, professors of electrical engineering at URI.
