MESA-500W EDXRF Element Analyzer from HORIBA

HORIBA Scientific has launched MESA-500W Energy Dispersive X-Ray Fluorescence Element Analyzer which is capable of handling liquid, solid and powder samples through a single touch fully automatic operation. In other words, it does not require any special expertise to operate the system. In fact, even novice users can operate the MESA-500W to make accurate measurements.

Xerophy, a high purity silicon detector, is integrated within the analyzer. The system is suitable for a wide range of applications, including compositional examination of gems and ceramics, assessment of constituents of iron and steel products, and assessment of impurities in foods.

Key Features

Product features of the MESA-500W Energy Dispersive X-Ray Fluorescence Element Analyzer are:

  • Provides one touch measurement of all elements ranging from sodium to uranium
  • Samples can be simply placed in the chamber for instant measurement
  • 5 mm irradiation diameter collimator provides improved X-ray intensity
  • Vacuum monitor continuously ensures optimum conditions for accurate assessment
  • Fundamental Parameter Method (FPM) quantitative analysis does not require any standard samples
  • X-ray tube current is automatically set to optimum level for all types of samples
  • High purity silicon detector removes the necessity for continuous supply of liquid nitrogen
