Fischerscope XAN 220

Gold Purity Analyzer

Gold testing machine in assaying centres: XAN220 is available in various technical specifications these are widely used for fast and non-destructive analysis and coating thickness measurement of gold and silver alloys. These are optimized X-ray fluorescence measuring instruments, acclaimed for compact size and consistent performance.

These are widely used for the analysis of precious metals and their alloys in composition and coating thickness and used for the measurement of up to 24 elements in the range of chlorine (17) to uranium (92). Our products are extensively acclaimed for its excellent accuracy and long term stability.

These are admired for high functional efficiency, time saving quality and effective usage. Owing to its good detection sensitivity and high accuracy, these are widely recommended by large numbers of clients.

  • These are user-friendly bench-top instruments available in various housing size and support stage.
  • These are extensively recommended by clients owing to its quick and easy sample positioning.
  • These are available in different range including XAN 220 and XAN 222, which are fitted with small parts and for quick and easy sample positioning.
  • The X-ray source and semiconductor detector assembly is located in the instrument‘s lower chamber.
  • These are straightened with the integrated video microscope with zoom and crosshairs simplifies sample placement and allows precise measuring spot adjustment.
  • These are operated through the powerful and user-friendly WinFTM® software.
