Synthesis of portable x-ray fluorescence spectrometry and visible near infrared diffuse reflectance spectroscopy for soil chemical characterization

Background: Traditionally time-consuming lab-centered routines that are based on raster sampling and wet chemical analysis are utilized for a comprehensive physicochemical soil analysis. However these methods are time consuming and highly expensive and thus not practical nor convenient for the mapping of soil properties over large areas. The disclosed technology solves this issue by proposing a prototype that will merge data from both the Portable X-Ray Fluorescence and the Visible Near Infrared Diffuse Reflectance Spectroscopy (henceforth referred to as PXRF and VisNIR DRS respectively) thus allowing for a rapid in-situ soil analysis and characterization. Technology Description: This technology merges data from both Visible Near Infrared Diffuse Reflectance Spectroscopy (VisNIR DRS) (350-2500 nm) with data from Portable X-Ray Fluorescence Spectrometry (PXRF) into proprietary algorithms for rapid on-site characterization of soil chemical and physical parameters. This is a dual VisNIR/PXRF sensor system which integrates data seamlessly on-site using both data sets for optimized predictions of soil properties. Applications: 1) Transportation industrial and energy storage industries 2) Grid energy storage systems especially with the upcoming intermittent renewable energy sources. Patent Status: A provisional patent 62/013692 was filed on 06/18/2014.
