Analytical Chemistry Workshop for Students and Faculty June 28-29,1983, Boulder, Colorado The University of Colorado invites undergraduate chemistry students and their professors to apply for par ticipation in a two-day analytical chemistry workshop at the University of Colorado, Boulder. The costs of the two-day workshop, lodging in a mod ern, air-conditioned dormitory, and all meals over the two days will be pro vided through a grant from the Mon santo Company for the 100 partici pants selected. Participants need only provide their own transporation to and from Boulder. Monsanto's inter est in funding the workshop arose from the company's participation in the Allerton analytical conferences. Student participants will have a unique opportunity to acquire first hand knowledge about recent develop ments in analytical chemistry and to learn of the career opportunities in this area in industry, government, and academia. Faculty participants can take ad vantage of a unique opportunity to update their knowledge of recent ad vances in analytical chemistry and to better counsel students regarding op portunities and rewards in the field. The Workshop The workshop will consist of lec tures, panel discussions, laboratory demonstrations, and tours of laborato ries in the Boulder area, including de scriptions of recent advances in ana lytical chemistry and instrumentation, current research, and analytical chem istry as a profession. Speakers and topics, as presently scheduled, are given below: • Lasers in Analytical Chemistry— Murray Johnston • Electrochemical Methods of Energy Conversion—Carl Koval

Focus • New Chemiluminescence Meth ods—John Birks • GC/MS, MS/MS, and Environmen tal Analytical Chemistry—Robert Sievers • Liquid Chromatography and Drug Analysis—Harold Walton • Electronics for Chemists—James Avery • Data Analysis, Pattern Recognition, and Artificial Intelligence—Robert Meglen Industrial chemists and faculty from other universities will be invited to participate in two additional panel discussions, on employment as a PhD analytical chemist in an industrial and in an academic setting. Selection Criteria Chemistry undergraduates and their professors are invited to apply. Students should have shown a high level of competence in chemistry and should have a desire to pursue gradu ate work in chemistry, with possible interest in analytical chemistry. Stu dent candidates should ask one pro fessor to send a letter of recommenda tion describing the student's perfor mance in chemistry and potential for graduate studies. Preference will be given to students in their junior year who are accompanied by their profes sors. Others will be considered as space and funds permit! A limited number of professors not accompanied by a student will be admitted and vice versa. Applicants with similar quali fications will be selected according to the postmark on the application. How to Apply Fill out and send the attached ap plication. Applications should be sub mitted as soon as possible, but must be received by March 31,1983, to en sure consideration. Notification of ac ceptance will be sent by April 15, 1983. The University and Its Location The main campus of the University of Colorado is located in Boulder, about 25 miles northwest of Denver. A city of about 84 000 people, Boulder is widely recognized as enjoying an ideal geographical setting. Situated at the eastern edge of the Rocky Mountains at an altitude of 5450 ft, it has sunny, dry summers. Many summer recre ation areas are nearby, including Rocky Mountain National Park. Dur ing the workshop a free cookout on Flagstaff Mountain is planned. Boulder has become a scientific cen ter for the Rocky Mountain area. Close cooperation exists between the
university and the Boulder laborato ries of the National Oceanic and At mospheric Administration (NOAA), the National Bureau of Standards (NBS), and the National Center for Atmospheric Research. The Joint In stitute for Laboratory Astrophysics and the Cooperative Institute for Re search in Environmental Sciences, co operative institutes of the university and the NBS, and the university and NOAA, respectively, are located on the campus. Major companies have scientific laboratories in the area in cluding IBM, Ball Brothers Research Corporation, Beech Aircraft Corpora tion, Storage Technology Corporation, and the Syntex Corporation. Tours of
some of these organizations are planned. Graduate Study and Research in the Department of Chemistry As a participant in the program you will be able to obtain firsthand knowl edge about the university and the de partment of chemistry. The depart ment offers graduate work leading to MS and PhD degrees in analytical chemistry, biochemistry, chemical physics, environmental chemistry, in organic chemistry, organic chemistry, and physical chemistry. A list of re cent publications is contained in the American Chemical Society's "Direc tory of Graduate Research."
Recent Advances in Size Exclusion Chromatography Microparticulate columns, more powerful detectors, and more sophisticated data systems At last November's Eastern Analyt ical Symposium (EAS), a session enti tled Recent Advances in High-Performance Size Exclusion Chromatogra phy (SEC) brought together a number of well-recognized authorities on the separation and characterization of polymers. Over the past decade, more efficient packings, more powerful de tectors, more sophisticated data sys tems, and a series of other improve ments all have contributed to the evo lution of conventional SEC into highperformance (HP) SEC. According to Ronald E. Majors of the Varian In strument Group, who organized and chaired the symposium, "Some prac ticing polymer chemists and analytical chemists are unaware of the great strides that have been made in SEC column technology and instrumental development in the last several years." SEC has long been the preferred liquid chromatographic (LC) method for separating high-molecular-weight polymers and determining their mo-

lecular weight (M) distributions. But the technology has changed quite a bit since the days when the only SEC col umns available were 4 ft long with 40-70-μηα particle diameter (dp) packings; working volumes were 50100 mL for complete elution of a typi cal sample on a set of columns. With HPSEC, the columns are only 1-2 ft long, the packings are "microparticulate" (5-10-μπι dp), and a typical working volume is only 1-10 mL. "Separations and polymer character izations that used to take hours on long columns can now be performed in less than a half hour," said Majors. The revolution in SEC began about 10 years ago with the advent of microparticulate packed columns. Mass transfer, the exchange of polymer mol ecules between the interstitial volume and the pores of the packing, which results in chromatographic separation, is slow with the large-size particles used in conventional SEC.
