NEWS exchange resins are widely used industrially, there are difficulties in obtaining special resins or getting them developed for analytical work. Dr. Kraus outlined three developments which may have analytical applications—ion exchange membranes now used industrially in desalting, ion exchange resins which can be used to dissolve precipitates, and a new spot Test technique employing a resin bead containing suitable spot test reagents which concentrates the ions of importance and results in a gain of two orders of magnitude in sensitivity of The tests.
Spectroscopy Conference The fifth annual Rocky Mountain Spectroscopy Conference will be held at the Olin Hotel in Denver, Colo., on August 6 and 7.
