Engineered to meet the rigorous technical demands of the analytical instrumentation industry
High resolution spectral data for sharp feature recognition
The QualitySpec Trek is a truly portable full-range contact spectrometer that is fast, accurate and easy to use.
The cost-effective solution when precision benchtop analysis is essential
With its capacity to detect small concentrations of organic and inorganic compounds as well as contaminants, high resolution reflectant spectroscopy has long been a core technology of soil characterization studies. Today, with the growth and availability of soil spectral libraries from around the world and countless labs developing custom quantitative calibration models for the interpretation and application of spectra to soils analysis, rapid and accurate in-situ soils characterization has become a reality. Quantitative models allow calibrations based on as little as 100 selected characterized samples to be applied to the rapid analysis of thousands of samples, in the field or in the lab. Coupling this technology with hyperspectral imagery, ground truthing, and advanced spatial statistical methodologies has resulted in a greatly improved capacity for large area soil assessments.
Maximize your resources, save time and money, and realize the strategic value of rapid on-site analysis. Field portable near-infrared (NIR) spectroscopy with quantitative calibration models breaks the bottleneck of sample collection for lab-based testing, minimizing lab-related project costs, while providing analysis results to the field survey work-flow.
The World Agroforestry Centre, with support from the Rockefeller Foundation, has produced a remarkable set of breakthroughs in tools for rapid large area assessment of soil quality and organic resource quality using the FieldSpec Vis/NIR full-range spectrometer (Shepherd & Walsh, 2002). The characteristics of soil spectra are controlled by mineral composition, organic matter, water (hydration, hygroscopic, and free pore water), iron form and amount, salinity, and particle size distribution. These attributes of soil basically determine their capacity to perform production and environmental functions. Calibration techniques, based on new pattern recognition algorithms, have been developed so that multiple soil attributes can be assessed from this single measurement (Shepherd & Walsh, 2002). Soil functional attributes such as aggregate stability, soil infiltration rate, and soil respiration rate can also be related to soil reflectance in a number of studies.
To accommodate a range of possible application requirements, ASD offers a variety of precision instrument solutions.
For lab-based or on-site research and analysis such as calibration model development, our LabSpec line of laboratory instrumentation offers research-grade instrument performance in a rugged package suitable for transport to the sample location. LabSpec® analytical instrumentation delivers precision visual near-infrared (VNIR) reflectance measurements for rapid, non-destructive materials analysis.
When in-situ analysis is required or ground surveys are being coordinated with over flight data acquisition, the ASD FieldSpec line of spectroradiometers offers a wide range of configuration options for contact reflectant, radiance, and irradiance measurements. With a customized backpack, portable power supply, and wireless communication with the instrument controller, ASD brings your lab to the field and your results to you instantly for data-backed decision making, maximizing your field time and budget.
