Advisory Board
Seven new members from government, academia, and industry have been selected to serve three-year terms on Analytical Chemistry's Editorial Advisory yoard. Each January, membership is rotated as new appointees replace members whose terms have expired. The chairperson of the ACS Division of Analytical Chemistry serves a one- year term as ex officio representative of the Division. Established in the 1940s to advise the Journal's editors, the board meets formally once a year at ACS headquarters. The board members are a vital link between the editors and the analytical chemistry community, providing guidance and advice on editorial content and policy.

Chief, Air Toxicants Branch - CDC The National Center for Environmental Health, Centers for Disease Control and Prevention (CDC) is accepting applications for a senior laboratory scientist to become Chief of the Air Toxicants Branch. This unique laboratory is engaged in developing methods to measure volatile organic compounds (VOCs) and products of tobacco smoke in human blood and urine and in applying the methods to populations with known or suspected exposures. The branch has a staff of 20 people (4 Ph.D.s) and state of the art instrumentation (4 modern mass spectrometers). In addition to scientific direction of the group, the chief will interact with other Federal and state agencies and international programs involved with environmental and smoking issues. Candidates should have advanced training in chemical/analytical sciences documented experience in the analysis of VOCs and/or tobacco products in human samples and experience managing laboratory professionals and scientific programs Salary range $63,675 - $97,368, depending on qualifications.

Robert Kellner We regret to report that Robert Kellner of the Vienna University of Technology (Austria) died Oct. 8, at the age of 52. His untimely death was a shock to all who knew him as an extraordinary, active man. Kellner was born in Vienna on Jan. 5, 1945. After receiving his Ph.D. in chemistry from the Vienna University of Technology in 1971, he achieved his "Habilitation" in 1975 under the supervision of H. Malissa. Kellner was appointed professor in 1978. Kellner had a successful career, including more than 200 publications, numerous lectures, and international conferences, many of which he helped organize. His commitment to teaching analytical chemistry culminated in EUROCURRICULUM and a textbook that will be presented at the 1998 Pittsburgh Conference. Kellner also helped initiate the Working Party of Analytical Chemistry (WPAC) of the Federation of European Chemical Societies. WPAC's growtii and development during the past few years and its transformation into the Division of Analytical Chemistry can be traced back to Refiner's initiatives All who knew Robert Kellner will remember him as a hard-working scientist a reliable colleague and a true friend Manfred Grassernbauer and Friedbacker
