How do you get the highest resolution consistently in ion exchange chromatography?
News 27th Pittsburgh Diffraction Conference The 27th Pittsburgh Diffraction Con ference will be held November δ through 7, 1969, at Mellon Institute, Carnegie-Mellon University, Pitts burgh, Pa. Papers on any aspect of diffraction, microscopy, small angle scattering, crystal physics, and chem istry, or related applications and in strumentation are being solicited. Ab stracts of 400 words or less should be forwarded to the program chairman, John L. Bomback, U.S. Steel Corp., Fundamental Research Laboratory, Monroeville, Pa. 15146, before Sept. 8. A symposium on ESCA, electron spectroscopy for chemical analysis, will be held Thursday, Nov. 6. Outstand ing speakers will present invited papers on electrons produced by X-ray excita tion, applications to metals, and mo
lecular orbitals and Auger electrons. A special session on ultra structure of membranes by electron microscopy and X-ray diffraction is also planned. Guest speaker for the Thursday evening meeting following the banquet is M. Kent Wilson, head of the chem istry section of the National Science Foundation. Nominations for the Sidhu Award are requested in the form of one-page re sumes of the candidate who must have made an outstanding contribution to the field of diffraction and be under 33 years of age. Nominations should be sent to the program chairman before July 1. A confidential employment register will be maintained and employment op portunities are requested for posting. Please address inquiries to John H. Scott, U.S. Steel Research Center, Monroeville, Pa. 15146.
Only by using Bio-Rad AG® resins! BIO-RAD AG resins represent the highest level of purity available for ion exchange chromatography. AG resins are exhaustively purified and sized to specific ranges to assure sharp resolution and highest reproducibility. For example, the maximum iron con tent in AG-1 anion resin is 0.00005%. For the full story on BIO-RAD and its role in ion exchange technology—in cluding valuable data on Bio-Rex resins, specialty resins, resin selection, regeneration and applications—send for our general catalog, Price List T.
