The Vanta GX analyzer has been designed in such a way that it provides strong features in a small countertop system for secure and trustworthy precious metals testing. Users are not exposed to radiation since the system uses X-Rays in a regulated setting:

  • During testing, the analyzer locks tightly and only permits X-Ray emission when the lid is closed
  • The instrument’s front and back have bright safety lights that flash when X-Rays are being released
  • The X-Ray shielding glass window safeguards the user while allowing constant viewing of valuables for better customer trust

The Science Behind the Technology

X-Ray fluorescence, otherwise called XRF, is a nondestructive method for elemental analysis that has been utilized in the family of Vanta™ analyzers.

All Vanta analyzers utilize the proprietary Axon Technology™ for improved XRF signal processing. Ultra-low-noise electronics drive the boundaries of X-Ray detector performance, heading to higher X-Ray counts per second and faster and reliable outcomes.
