SIEMENS
Some X-ray diff ractometers cost more than others because, quite simply, some are better than others. Siemens has effectively used its many years of diffractometer development and manufacturing experience to create the D 500—a diffractometer of superior construction. Its outstanding design means greater accuracy during all phases of material examination; such as qualitative analysis of compounds or phases, quantitative measurement of mixtures, study of lattice constants and line profile effects and evaluation of orientation or stress. Siemens D 500 has been designed to permit flexible operation in three modes—fully automated, semi-automated or manual. In the fully automated mode the software utilizes BASIC language which is easier to use than the FORTRAN language in other systems.
Simplicity and ease of operation mean you can concentrate on analytical problems instead of equipment operational problems. t h e D 500 can operate in either a horizontal or vertical position and because the X-ray
tube is integrally mounted to the diffractometer, the position may be changed while maintaining the alignment of the instrument. The D 500 is available with 1, 40 or 80 specimen magazines, each with sample rotation capabilities.. . perfect for the routine analysis of a large number of samples. A specimen holder for sample sizes of up to 50 mm by 50 mm by 8 mm is standard equipment for the D 500. And the 0, 20 motors operate at a high speed of 400 degrees/minute as well as a variety of independently selected scan speeds.
