Kratos Analytical - Sequential X-Ray Fluorescence Spectrometer XRF-1800

Year of introduction
Status available
Company Kratos Analytical
Categories X-ray spectrometer: XRF
New XRF with local analysis and mapping capabilities as standard features.

Features
  • Reliable Analysis of a local area only 250µm diameter in wavelength dispersive mode - a world first!  The original high sensitivity aperture and accurate sample positioning capability of the XRF-1700 is now improved in the XRF-1800, enabling any user selected part of the sample to be analyzed reliably and also provide high performance element mapping. An optional CCD camera may be used to observe the sample
  • High sensitivity, high resolution, and high precision ensured by new optics  The X-ray beam path length is minimized increasing sensitivities for all the elements. High sensitivity and resolution are ensured over the entire wavelength range. Three selectable slits are provided: Standard Slit - High Sensitivity Slit - High Resolution Slit
  • Five apertures, with openings of 0.5, 3, 10, 20, and 30mm diameters are selectable to ensure high sensitivity in analysis, even of samples with a very small diameter
  • 4kW X-ray tube with a thin window offers high reliability and long life  The sensitivity is more than 30% higher compared with a conventional 3kW X-ray tube.
  • Rapid qualitative analysis ensured by ultrafast scanning speed - 300 °/min  The elements ranging from Be to U are qualitatively determined in only two and a half minutes. Semi-quantiative determination is made possible using the fundamental parameter (FP) method, which requires no standard samples in the same time.
  • Determination of C,H,and O in organic samples  Shimadzu's original integrated intensity measurement method and background fundamental parameter method enable carbon, hydrogen, and oxygen in organic samples to be reliably and quanitatively determined.
  • High performance analysis through simple operation  A workstation based data system that operates in multitasking and multiwindowing environments ensures outstanding ease and simplicity of operation.
