IR spectroscopy

Visible and near-infrared (VIS-NIR) spectroscopy can detect the presence and relative abundance of clay minerals, micas, carbonates, sulfates, iron and copper oxides, organics, and many hydrous and hydroxyl-bearing minerals. We will analyze your sample quickly and effectively using an ASD FieldSpec Pro FR portable spectroradiometer with a wavelength range between 350 and 2500 nanometers. Send us samples or we can visit your site. All studies include interpretation of spectra and discussion of the geological context. Combine VIS-NIR with our petrographic services and we will give you a 40% discount!

Key Benefits

	Rapid acquisition of data (no sample preparation)
	Field portable (on-site analyses)
	Delineate alteration zonation in the field. Outcrops that cannot be reached on foot can be analyzed from afar.
	Laboratory-quality spectra. Click below to see examples.

Capabilities

The ASD FieldSpec is significantly faster and has better signal to noise characteristics than the PIMA spectrometer. Also, a wide variety of light sources can be used to illuminate the material to be analyzed, including natural sunlight. This makes the FieldSpec an ideal tool to calibrate satellite images, analyze materials from great distances (i.e. bench mapping where no foot access is possible), and provide quality control along the production line in industrial settings.

Applications

Mining, Petroleum, Geothermal Energy Industries

	IR analysis of diamond drill core. Depending on your sample interval, thousands of meters of drill core can be analyzed per day.
	IR analysis of reverse circulation chips or sample rejects. This is the fastest mapping method available. Our experience indicates that over 3,000 meters of reverse circulation holes can be mapped per day.
	Bench and general field mapping. Entire open pits or prospects can be mapped rapidly to delineate ore, alteration zones, regions with high fines generation potential, etc. The FieldSpec can be connected directly with a GPS, so sample position will be recorded directly with the spectra.

Specifications

	The ASD FieldSpec Pro FR portable spectroradiometer with a spectral range of 350 - 2500 nanometers, 2 nm sampling interval convolved to 1nm, and 10 nm spectral resolution. For more detailed specifications, visit the Analytical Spectral Devices web site.
	All data can be delivered in the ASD file format, .txt files, or a variety of other formats. We will send you graphs of individual spectra, geologic maps, or all of the above, depending on your needs.
