ED-XRF (Energy Dispersive X-Ray Fluorescence) is a non-destructive analytical method. The electron response of single atoms in a gemstone or mineral on incident X-ray radiation. The resulting fluorescence X-ray spectrum provides the chemical composition of all the elements of any sample within seconds.

Applications:

  • Separation of natural gemstones from synthetics.

  • Analyzing enhancement methods in a gemstone.

  • Analyzing the geographical origin of a gemstone.

FTIR

AIGS : AIGS Lab Technology

Fourier Transform Infrared Spectroscopy (FTIR) is used to obtain an infrared absorption or emission spectrum from a solid, liquid or gas.

Applications:

  • Separation of natural gemstones from synthetics.

  • Determining the presence of polymer-based impregnation, eg: Jade & Emeralds.

 

LIBS

AIGS : AIGS Lab Technology

Laser-Induced Breakdown Spectroscopy (LIBS) uses a highly energetic and focused Nd:YAG laser pulse to ionize a small number of particles on the sample’s surface. As this plume expands, the expelled particles become excited before almost immediately dropping back down in energy and releasing photons. As the specific frequency of this emitted light varies from element to element, LIBS can, in principle, determine the composition of any mineral.

Application:

  • Detection of diffused beryllium within corundum (i.e. “new heat”) when present at quantities in excess of 2 ppm.

DFI

AIGS : AIGS Lab Technology

The DFI Mid-UV Laser a flexible, high-performance device for detecting HPHT and CVD synthetic diamonds of any size, and is able to test up to three thousand melee stones per hour.

Applications:

  • Detection of synthetic colorless diamonds produced via both the CVD and HPHT methods.
  • Detection of imitation diamonds.

UV-VIS-NIR

AIGS : AIGS Lab Technology

UV-VIS-NIR spectrometer is used to measure the light absorption and intensity in UV and white light. This measurement allows us to identify certain chemical elements in the sample.

Applications:

  • Separation of natural Ruby, Sapphire and Emeralds from synthetics.
  • Detecting the presence of trace elements to determine if the sample is Metamorphic or Basaltic.
