EXPOCHEM EXPOCHEM '79, an international exposition of analytical instruments for industrial and biomedical laboratories, will be held at the Astrohall in Houston, Tex., October 22-25,1979. This scientific exhibition will embrace all areas of modern analytical instrumentation. The scientific part of EXPOCHEM '79 will include 16 symposia on a wide variety of topics. Each morning session will open with a plenary lecture which will discuss the contemporary aspects of the subject. Outstanding researchers from the U.S. and Europe will participate in the technical program. Although more than 3700 hotel rooms have been reserved for this meeting, early arrangements for housing accommodations should be made. Preregistration for the meeting is also urged so that long delays can be avoided. Registration forms for the hotel and exposition may be obtained from: Dr. Albert Zlatkis, Chemistry Department, University of Houston, Houston, Tex. 77004 (713-749-2623). Short courses covering nine separate topics will be held on October 20-21, before the meeting. For details, see page 736 A, this issue. The following pages of ANALYTICAL C H E M I S T R Y contain the complete technical program for EXPOCHEM '79.

Just what you need to automate HPLC. Inject samples. Switch columns. Select solvents. All automatically with Rheodyne valves. Rheodyne's pneumatically-actuated valves enable you to introduce automatic stream control anywhere in your HPLC system. They work at pressures up to 7000 psi — offering many opportunities to save time and increase precision through automation. Automatic sample injection. Done with Rheodyne Model 7010A. a pneumaticallyactuated version of our popular loop-type injector. Excellent for use with an autosampler in routine analysis. Very helpful for inject ing the same sample repeatedly in methods development. Removable sample loops in eight sizes from 10 μΙ to 2 ml insure that successive samples will be exactly the same volume. Automatic column switching. Our 7000
Series valves will switch columns in and out of the stream to increase the speed of analysis. For example, two columns can be interfaced to analyze complex samples without employing gradient elution. Or asmall column can be used to enrich and pre-fractionate a sample before switching the stream to an analytical column. Automatic solvent selection. With Rheodyne's 5012A all-Teflon 6-position valve you can select any of six different solvents during automated methods development. Or automate many stepwise elution schemes of your own design.

Trends in Federal R&D Funding Since Federal funds continue to un derwrite one-half the research and de velopment effort in the nation, trends in Federal R&D funding are of inter est to the scientific community in gen eral and to analytical chemists in par ticular. The NSF has released a report that provides data on trends within R&D functional areas (such as health, envi ronment, and energy development and conversion), and on shifts in funding between different areas. The report includes data on the 1979 Presidential budget, and on subsequent congressio nal actions that had apparently changed funding levels at publication time. Copies of the report, "Analysis of Federal R&D Funding by Function: Fiscal Years 1969-1979," are available from the Superintendant of Docu ments, U.S. Government Printing Of fice, Washington, D.C. 20402.

Stuart Borman Joins AC staff ANALYTICAL CHEMISTRY'S new
assistant editor, Stuart Borman, earned his bachelor's degree in chem istry (summa cum laude) at Hunter College of the City University of New York. Stuart was a Federation of Analyti cal Chemistry and Spectroscopy So cieties (FACSS) student awardee in 1976, and that summer he served as an ACS Analytical Division Summer In tern in Analytical Chemistry at Stauffer Chemical Co.'s Eastern Research Center in Dobbs Ferry, N.Y. He has done graduate work in ana lytical chemistry at Indiana Universi-

Pittsburgh Conference Moves to Atlantic City Harold Sweeney, President of the 1980 Pittsburgh Conference on Ana lytical Chemistry and Applied Spec troscopy, has announced that next year's meeting will be held in Atlantic City, N.J., March 10 to 14. Many fac tors were involved in the decision to move from Cleveland, where the meet ing has been held for more than 10 years. Not the least of these were the severe housing problems encountered by attendees. Atlantic City offers excellent exhi bition and meeting room facilities and can accommodate the thousands of participants in new and refurbished hotels.
