Analytical Techniques and Advanced Instrumentations

The Report is the maximum expression of a long and sophisticated work, made of investigations with the classic gemologist tools plus a series of lines composed of advanced instrumentation.
In the daily routine, GIG teams of gemologists, in addition to the microscope, the refractometer and other tools, utilized many complex instruments and consequently applied specific analytical techniques.

Micro-Raman Spectroscopy: the micro Raman Spectroscopy is analytical technique able to identify the materials, without samples preparation. Not destructive test.

GIG Research Department is equipped with a In-via Con-focal Raman, made by Renishaw Company, coupled with Leica optical microscope and endowed with two different laser sources.

FTIR Spectroscopy: the FTIR Spectroscopy is a one of the most suitable analytical technique for the materials characterization.

GIG Research Department is equipped with FTIR Spectroscopes and a micro FTIR/ATR coupled system, endowed with the accessories to perform the analyses on prepared and not prepared samples as well.

UV-Vis/NIR Spectroscopy: the UV Vis/NIR Spectroscopy aims to observe and characterize several elements present in the samples (i.e. the chromophore groups), on the basis of the absorption’s bands.

The spectrometers installed at GIG Research Department are able to analyse a large portion of electromagnetic spectrum, on prepared and not prepared samples as well.

Chemical Characterization: GIG Research Department is equipped with a Quant’X ARL ED XRF, made by Thermo Fisher Company.

This instrument is able to perform qualitative and quantitative analyses, detecting trace elements from sodium, on polished as well as not prepared samples.

High-Tech Imaging : GIG Research Department is able to perform different type of imaging samples studies:

– Optical M microscope imaging (high magnification)

– Fluorescence and phosphorescence imaging (standard and magnification views). Browse GIG Gallery to enjoy some samples.

– Color observations by international recognized standards methods.
