Naturally occurring minerals in the Earth’s crust contain unique chemical signatures, which can reveal detailed information about the history of their formation and geographic origins.

In this free eBook, discover a suite of analytical technologies designed to assess the properties and composition of various minerals to help researchers understand how their instruments can be used for the analysis of gemstones for the jewelry industry, as well as basic research into the mineralogy of both volcanic and metamorphic rocks.

This eBook will also cover:

  • Spectrophotometric analysis of gemstones
  • X-ray analysis of precious stones
  • Elemental mapping
  • Electron probing of minerals in volcanic rocks

Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses. Find the best IR spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters. Find the best particle characterization instruments in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.SpectrophotometrySpectrophotometry is a technique used to measure the absorption or transmission of light through a sample. It is commonly used in chemical analysis, environmental monitoring, and quality control.
