Big step in making washdays easier

Quality of modern detergents is accurately controlled with G-E x-ray diffraction units

HE girl's hands in the above photograph are loading a sample holder in the laboratory of a detergent manufacturer. Every day carload shipments of these washday products must be checked to insure housewives of unvarying quality. This is an exacting job because the modern 'detergent is a mixture of perhaps half dozen sodium polyphosphates. These vary considerably in their properties, even though chemically similar. By providing a fast, exact, low-cost analysis of their crystalline structures, x-ray diffraction overcomes a formidable laboratory problem. Many other industries now look to x-ray diffraction for both research and production control. On such widely diverse products as antibiotics and ceramics, paper and titanium, plastic and petroleum — this flexible, yet highly accurate, non-destructive technique is used. If crystal structure, atomic configuration or molecular orientation are factors in the materials you process, get all the facts on x-ray diffraction. See your G-E x-ray representative, or write X-Ray Department, General Electric Company, Milwaukee 1, Wisconsin, Room UU44.

General Electric XRD-3D provides a direct measurement of the diffracted intensities of crystalline materials. Variations of the basic unit permit the recording of the results on film and also the direct measurement of fluorescent x-ray spectra.
