170th National ACS Meeting Chicago, III. August 24-29, 1975 The Analytical Chemistry Division of the American Chemical Society will hold 19 half-day sessions with more than 100 papers at the Fall National Meeting in Chicago. Several sessions have been jointly planned with the probationary Division of Computers in Chemistry. The latter division is primary sponsor of two sessions which will deal with "Getting Started in Minicomputers," whereas the Analytical Division is primary sponsor of two sessions on "Prospects of Microprocessors in Analytical Chemistry." In yet another session, sponsored solely by the Analytical Division, the computer plays a part: "Spectral Interpretation by Computer." On Thursday a symposium on "Therapeutic Monitoring of Clinical Drug Levels" has been planned in cooperation with the American Association of Clinical Chemists. In addition to the above joint symposia, the fall meeting will feature symposia on lasers in chemical analysis, multielement analysis, chromatographic analysis of biologically important compounds, current analytical problems and new approaches in nuclear technology, and "The New Face of Analytical Chemistry." Three general sessions will be held Thursday morning and afternoon and Friday morning.

All Analytical Division sessions will take place in the Pick-Congress Hotel with the exception of the two joint sessions planned with the Probationary Computers in Chemistry Division as primary sponsor which will be held in the LaSalle Hotel. The Analytical Division social hour and dinner will be held Wednesday, August 27 at 6:00 and 7:00 p.m. at the Pioneer Courts Restaurant, 401 North Michigan Ave., Chicago, 111. 60611. Newly elected officers of the Division will be introduced, winners of Graduate Fellowship Awards will be announced, and John Ferraro of Argonne National Laboratory will be the keynote speaker. In conjunction with the ACS meeting, there will be a National Chemical Exposition at the Conrad Hilton Hotel, August 26-28. Commercial exhibits will be augmented by a special presentation giving advances in research and a series of poster sessions (a novel way of presenting papers). The detailed technical program given below includes all the Analytical Division sessions including those jointly sponsored with other ACS divisions. It also includes sessions which are relevant to analytical chemistry in the programs of the Divisions of Fertilizer and Soil Chemistry and Petroleum. The former division has a ses-

sion on "Testing and Analyses of Fertilizer Materials" on Tuesday; the latter division has sessions on "Chemistry, Occurrence and Measurement of Polynuclear Aromatic Hydrocarbons" on Thursday. Preregistration forms and housing information are contained in Chem. Eng. News, June 9,1975. The complete technical program for the meeting appears in Chem. Eng. News, July 21, 1975.

from Bio-Rad New Bio-Lyte® carrier ampholytes for isoelectric focusing are now available from stock in one wide working pH range (Bio-Lyte 3/10) and in six narrow pH ranges, Bio-Lyte 3/5, 4/6, 5/7, 6/8, 7/9 and 8/10. (The product designations are indicative of the working pH range.) Made of polyamino-polysulfonic acid, the Bio-Lytes are ideal for use with a polyacrylamide gel as the stabilizing medium, either by substituting directly for the ampholytes you are now using, or by following the suggested formulations in Bio-Rad's Bulletin 1030 or in the instructions that accompany each Bio-Lyte shipment. Bulletin 1030 has all the details, including pH profiles, actual separations and complete pricing. It also contains information on the new Gel Pro-pHiler described below.

holds a cylindrical gel in position so you can measure the pH profile of a gel as soon as it is removed from its tube. When you are finished, the gel emerges virtually undamaged and ready for staining. If you are using isoelectric focusing, or if you suspect you should be, then write for Bulletin 1030. You'll find everything you need for this proven method of separating proteins.
