Twenty-eight X-ray analyses in 40 seconds... evaluation in 20 more.
You couldn't ask more from a multichannel X-ray spectrometer. Twenty-eight elements ... simultaneous quantitative analyses ... adaptability to qualitative analysis too ... simultaneous evaluation ... integrated computer... floppy disk with dual drives ... data display unit. Plus a great many other unique technical and operational features typical of Siemens innovation. The MRS 400 handles concentrations from the ppm range to 100% directly ... trace analyses in the ppb
or sub-ppb ranges with additional sample preparation. It features the highly recognized 4kW Siemens generator to power our 3kW end window rhodium or palladium X-ray tube; logarithmically bent focusing crystals; and our patented tandem flow counter for higher counting rates and resolution. The MRS 400 can be supplied with up to two computer controlled scanners (movable spectrometers). Its speed, sensitivity and versatility make it equally valuable in routine
analyses, quality monitoring, process control, or research. There is no finer, more complete X-ray spectrometer available today.
