crystalline analysis made easy This X-Ray Diffraction System takes t h e work out of a variety of studies. Non destructive identification of crystalline phases—alone, or in mixtures, analyses of mixtures in terms of crystalline components, and measurements of lattice spacings are good examples. Scan speeds up t o 8 degrees 2Θ per minute, fast recording speeds, easy and precise alignment of X-ray tube with sample, and continuously adjustable slits—these are a few of the advanced features t h a t make this eco nomical system so fast and easy t o use. Write today for complete details.
