Now . . . you can use in your labora tory the same precise technique that tests the purity of isotope labeled compounds in Tracerlab's own radio chemical operations. With it, you can scan a chromatograph strip . . . then, lay it beside the resulting recording trace for direct identification of each location of radioactivity. This new Tracerlab SC-S5 Chromatogram System has five components: 1. New SC-55 Chromatogram Scanner with variable collimator slit adjust able by external screw from 0.00" to 0.25" for securing desired de gree of definition 2. SC-59 Shielded Manual Sample Changer 3.

The XVIth International Congress of Pure and Applied Chemistry, to be held in Paris July 18 to 24, promises to be a large meeting with 900 scientific papers sent in by authors of 38 nations. Lectures on physical, inorganic, and organic chemistry will be given in addition to the papers, and four symposia will be held on scientific bases of elastomers, fibers, and plastic tests; electrochemical methods of analysis; criteria for the purity of proteins; and geochemistry. The program for the symposium on modern electrochemical methods of analysis is given below. Almost simultaneously with the congress, the X l X t h Conference of the International Union of Pure and Applied Chemistry will take place July 16 to 25 in Paris. Meetings are scheduled for the committees of the sections on physical, inorganic, organic, biological, and analytical chemistry. A number of excursions to places of interest in the area will be organized in connection with the congress, and a special program is planned for the ladies.
