News throughput due to a requirement for large column plate numbers and long separation times. Snyder also has made major contri butions to the theory and practice of gradient elution, including develop ment of the concept of linear solventstrength gradients for use in optimiz ing macromolecule separations. He also developed procedures for auto mated sample cleanup prior to HPLC and contributed to the understanding of sample dispersion in continuous flow analysis. Snyder received his BS and PhD degrees from the University of Cali fornia—Berkeley in 1952 and 1954, re spectively. He was employed by the Union Oil Company of California from 1957 to 1971, and by Technicon In struments Corporation from 1971 to 1982. Since 1982 he has been presi dent of his own firm, Lloyd R. Snyder, Inc. Snyder is coauthor of the popular textbook "Introduction to Modern Liquid Chromatography" and is a past recipient of the ACS Award in Petro leum Chemistry (1970), the Stephen Dal Nogare Award in Chromatogra phy (1976), and the Chromatography Memorial Medal, Academy of Sci ences of the U.S.S.R. (1980).
Summer Internship Program Seeking Applications The Division of Analytical Chemis try of the American Chemical Society will once again operate a program of summer internships aimed at intro ducing talented undergraduates to modern analytical chemistry. Stu dents chosen to participate in the pro gram will be employed by industrial, government, or academic analytical laboratories, where they will carry out various phases of fundamental or ap plied research in the analytical area. Laboratories participating agree to hire one or more students during the summer. Applicants are screened and evaluated by the Professional Status Committee of the Analytical Chemis try Division, and those students most qualified have their applications and reference letters sent to several of the participating laboratories. These orga nizations then select the individuals they deem suited for their particular needs and, via the Professional Status Committee, make contact with the students. The Professional Status Committee acts as a broker, soliciting applications from both students and organizations; salaries and details of
employment are negotiated by the or ganizations and the students. The Analytical Chemistry Division is seeking applications from interested students and the participation of in dustrial, government, and academic laboratories for the 1984 program. Student qualifications for the program include completion of at least the sec ond year of college, preferably includ ing an instrumental analysis course or its equivalent, and interest in analyti cal chemistry. Ideally, students should be between their junior and senior years at the start of the summer of 1984. The Analytical Division also is seeking applications from seniors graduating in 1984 who have specifi cally demonstrated their interest in analytical chemistry by application to graduate school with the intention of majoring in that area. Graduate stu dents in analytical chemistry will also be considered for the program, since it can provide a means of broadening their backgrounds. Deadline for student applications is Feb. 15, 1984.

F u s e d silica capillary columns gamma irradiated b o n d e d p h a s e s . . . NITRO-PAH/PAH MIXTURE
produce superior chromatographic separations with greater thermal stability—even at temperatures exceeding 300°C. Extensive studies by Foxboro/Analabs and leading chromatographers have shown that bonding via gamma irradiation offers superior levels of thermal stability, while eliminating the problems of possible polarity changes and residual column activity associated with organic peroxide initiated bonding methods. Foxboro/Analabs manufactures and stocks for prompt delivery gamma BoncTCapillary Columns with OV-1, SE-54, OV-1701, OV-17, and OV-225 gamma irradiated bonded phases. Most columns are available in lengths of 15, 25, and 50 metres. To learn more about our gamma Bond Capillary Columns and how they can improve separations and decrease analysis time, contact Foxboro/Analabs, 80 Republic Drive, North Haven, CT 06473, (203) 288-8463.
