概要

鉱山を探査する地質学者は、これらの機能強化により、探査対象や掘削現場でより迅速にデータを取得することができます。 ASD TerraSpec® 4 Hi-Res鉱物分光計がもたらすデータ品質の向上により、以前は測定が困難だった鉄を含有している低濃度で反射率の低い鉱物(蛇紋石や緑泥石など)を正確に評価することができます。 次のメリットがあります。

  • 強化された光学的配置により、より正確なスペクトル結果が提供され、高品質のスペクトルを明確に定義できます。
  • SWIR 1/SWIR 2領域での業界トップレベルの性能を誇り、卓越した変質鉱物識別を提供します。
  • 標準装備の高耐久スチールカバー光ファイバーにより、一貫したスペクトル品質が提供されます。
  • 試料調整が不要なため、迅速にフィールドスキャンを実行できます。

ASD TerraSpec 4 Hi-Res鉱物分析装置とSpectral GeoscienceのSpectral Geologist (TSG)ソフトウェアを組み合わせることでスペクトルを分析し、鉱物学的な生成物を製造できます。

Rapid Analysis Probe

Image

The Rapid Analysis Probe is specifically designed for speedy spectral collection of powders and other fine-grained materials such as small uniform seeds and grains. Its beveled tip and metal jacket greatly speed up the spectral collection process of fine grained materials to optimize workflow. Simply insert the Rapid Analysis Probe into your fine-grained media, collect the spectrum, use a chemical wipe to swipe the probe clean and move on to the next sample. It’s that easy! The Rapid Analysis Probe comes with a gimbaled white reference for high performance calibration. It can be used for quantitative predictive models.

If using this probe with a spectrometer such as a TerraSpec mineral analyzer or a LabSpec lab analyzer without an integrated light source, a Fiber Optic Illuminator is necessary. The Fiber Optic Illuminator provides the light source needed for sample collection.

ASD carries a wide array of calibrated and non-calibrated diffuse white and gray reference panels in varying sizes (from 2 x 2 in. to 12 x 12 in. or 5.1 x 5.1 cm to 30.5 cm x 30.5 cm) and reflectance levels, including encapsulated gray scale (NIST/NRC traceable) wavelength and USP standards for USP 1119. Calibrated panels come with certificate and documentation showing standard deviation and reflectance factors.

All reference panels and standards may be purchased separately. To provide our customers with a more cost-effective approach, specific sizes or styles of reference panels are included in accessory bundles designed for maximum compatibility with a particular application.

Your ASD sales representative will be able to advise you on the best option(s) for your needs.
