Energy dispersive x-ray fluorescence spectrometer, EDX-7000

Shimadzu (Japan)

Description

Energy-dispersive X-ray fluorescence spectrometers

The EDX-7000 and EDX-8000/8100 spectrometers, with measurable element ranges from Na to U and from C to U respectively, utilize silicon drift detectors (SDD) to achieve high sensitivity and are successfully used in various fields of science and industry requiring precise and rapid measurements without sample destruction.

Features

  • The high sensitivity of the instrument is achieved through the use of a high-performance SDD detector combined with optimized X-ray optics and primary filters.
  • Thanks to the high count rate of the SDD detector, productivity has increased tenfold.
  • The high resolution of the EDX-7000/8000/8100 spectrometers compared to previous models reduces peak overlap, improving the reliability of analytical results.
  • Since a thermoelectric system is used to cool the SDD detector, liquid nitrogen is not required.
  • The EDX-8000 spectrometer is equipped with an SDD detector with an ultra-thin window, enabling the detection of elements starting from carbon.
  • These spectrometers can analyze all types of samples — from micro to macro objects — in both liquid and solid states.
