Mid-infrared reflectance spectroscopy of synthetic glass analogs for Mercury surface studies

Mid-Infrared and Near-Infrared Diffuse Reflectance Spectroscopy for Soil Carbon Measurement

Diffuse reflectance spectroscopy offers a nondestructive means for measurement of C in soils based on the The ability to inventory soil C on landscapes is limited by the reflectance spectra of illuminated soil. Both the NIR ability to rapidly measure soil C. Diffuse reflectance spectroscopic (400–2500 nm) and MIR (2500–25 000 nm) region have analysis in the near-infrared (NIR, 400–2500 nm) and ...

Detection of mercury and other metals in mercury contaminated soils using mid-infrared spectroscopy

The Oak Ridge Reservation, established in 1942, was the designated site for the construction of the atomic bomb. During a 20-year period from 1944-1963 radioactive and toxic chemical pollutants, especially mercury compounds were released into the surrounding waterways. Mercury in the soil environment can undergo numerous chemical transformations. Conventional methods for detection of total soil...

Potential of Near-Infrared Reflectance Spectroscopy (NIRS) to Predict Nutrient Composition of Bromus tomentellus

Determination of forage quality of available species is one of the fundamentalfactors for the management of rangelands. Near-Infrared Reflectance Spectroscopy (NIRS)was used to analysis the Nitrogen (N), Acid Detergent Fiber (ADF), Dry MatterDigestibility (DMD) and Metabolizable Energy (ME) content of three phenological stages(vegetative, flowering and seeding) of Bromus tomentellus samples in ...

Development of near infrared reflectance spectroscopy (NIRS) calibration model for estimation of oil content in a worldwide safflower germplasm collection

The development of NIRS calibration model as a rapid, precise, robust, and cost-effective method to estimate oil content in ground seeds of worldwide safflower germplasm collection grown under different agro-climatic conditions was the key objective of this research project. The oil content was measured by accelerated solvent extraction method in a total of 328 samples collected across 2004 (16...
