X-ray analytical equipment is a big investment. Don't you deserve a look at the best investment? Whether it be spectrometers or diffractometers, Siemens analytical x-ray units are the best investment. Siemens SRS 200 is a sequential spectrometer that uses x-ray fluorescence methods to non-destructively analyze solid, powder, and liquid samples for all elements from fluorine to uranium. Sample changers are available to accommodate up to 80 specimens. That's flexibility. For process control applications demand-
ing speed and accuracy, the MRS 400 spectrometer provides up to 28 simultaneous analyses in less than one minute. That's speed. Siemens D 500 diffractometer provides for material examination; including structure and layer determination, texture and stress measurement, and phase analysis. The D 500 is available with 1, 30, or 80 specimen magazines, with sample rotation capabilities... perfect for the routine analysis of a large number of samples. All three units are designed and built to be either automatic or manual. So whenyou invest in an automatic unit, you get an automatic unit, not just a retrofitted manual instrument.
