Pittsburgh Conference
S o m e people at t h e P i t t s b u r g h Conference -will call it a whole n e w approach t o xray fluorescence analysis. We call it t h e EXAM S y s t e m . Elemental Xray Analysis of Materials is what EXAM is all about. Get simultaneous energy dispersive analysis (EDAX ) of all elements from Fluorine through Uranium. Qualitative analysis in seconds, quantitative to ppm in minutes for specimens up to 3" dia. and IV2" thick. See it in Booth 813 at the Pittsburgh Conference, or write for information to:

FORMA SCIENTIFIC, INC.
The Shandon Chromatogra phy Sample Streaker after Bacon is the simplest method yet devised for accurate quantitative control of sample streak ing for thin layer, preparative layer and paper chromatography. Rate of travel governs syringe discharge, producing absolutely uniform thin lines, precisely positioned, and done without a skilled operator. T w o styles available, both l o w in cost through functional design. Write for data bulletin to Shandon Southern Instruments, Inc., 515 Broad Street, Sewickley, Pa. 15143 (Pittsburgh District).
