Near-infrared spectroscopy is a highly flexible form of analysis, which can be applied to a broad range of research and industrial process applications

Near-infrared (NIR) spectroscopy is a highly flexible form of analysis, which can be applied to a broad range of research and industrial process applications. Long a staple technology in remote sensing, NIR spectroscopy has become popular within industrial markets as a cost-effective tool for measuring materials to optimize processes and manage costs.

What is NIR and how does it work?

NIR sp

ectroscopy is a method that makes use of the near-infrared region of the electromagnetic spectrum (from about 700 to 2500 nanometers). By measuring light scattered off of and through a sample, NIR reflectance spectra can be used to quickly determine a material’s properties without altering the sample.

NIR converts measured data into actionable information to help optimize processes or improve research. Capable of examining irregular surfaces with the same ease as a carefully prepared sample, NIR is non-destructive, and requires little or no sample preparation. It can also be used to analyze multiple constituents in a single scan.

Advantages of near infrared spectroscopy

• Highly flexible form of analysis
• Cost-effective
• Capable of examining irregular surfaces
• Non-destructive
• Requires little or no sample preparation

ASD FieldSpec range

ASD pioneered the science of field spectroscopy over 25 years ago and continues to lead the industry with the world's most trusted field-portable UV/Vis/NIR/SWIR spectroradiometers covering the full solar reflected spectrum.

The ASD FieldSpec 4 line of full-range spectroradiometers delivers the fastest and most accurate spectral field measurements available from any commercial field-portable spectroradiometer. Continued enhancements to core instrument spectrometers and other critical components have dramatically improved overall performance, signal, and integration speeds compared to earlier models.

ASD FieldSpec 4 spectroradiometers are designed specifically around the challenges researchers face when collecting spectral measurements in the field.

ASD TerraSpec range

The ASD TerraSpec line of mineral analyzers provide portable, rapid and non-destructive analysis of minerals in the lab or the field. Exploration geologists appreciate the ASD TerraSpec mineral analyzer’s portability and ability to rapidly identify key minerals. When used as an ore analyzer, results are presented in seconds to speed ore processing decisions.

ASD LabSpec range

The ASD LabSpec line of laboratory instrumentation offers laboratory-grade performance in a ruggedized, portable design suitable for benchtop analysis or transport to the sample location. ASD LabSpec analytical instrumentation performs rapid, non-destructive materials analysis for qualitative and quantitative applications.

The ASD LabSpec 4 product line utilizes the same spectrometer configurations as ASD’s FieldSpec line of spectroradiometers, long recognized as the “gold standard” in portable near-infrared (NIR) field spectroscopy. Employing this state-of-the-art NIR technology, these portable lab instruments can quickly and nondestructively measure a wide range of materials with absolute precision.

The ASD LabSpec spectrometer is easily adaptable for a wide range of analytical applications. For those applications requiring a spectrophotometer, the ASD LabSpec is available with a built in fiber optic light source.

Optimized for rapid analysis, ASD LabSpec 4 spectrometers are the ideal analytical instruments for fast-moving laboratory environments, providing instant results with no sample preparation.

• Evaluate hundreds of samples per day with high analytic throughput rates.
• Identify spectral characteristics of both liquids and solids in real-time.
• Non-destructive measurement means no sample preparation and allows for the reuse of the sample in other research.
• Measure multiple properties simultaneously through NIR energy that penetrates several millimeters into organic substances.
• Compatible with all ASD sampling accessories.
• Rapid analysis moves with the speed of production to evaluate incoming, in-process, or finished materials almost instantaneously.
