An apparatus and method include: receiving a data set having two or more variables; receiving a selection of at least one of the two or more variables, an abstraction level and a visual feature; automatically generating and displaying a set of visual representations of the data set on the display; receiving a change in the selected variables, selected abstraction level, the selected visual feature, or a selection from various views; determining a visual representation recommendation based on the selected variable(s), selected abstraction level and the selected visual feature, the change in the selected variables, selected abstraction level, the selected visual feature, or the selected views; and automatically updating and displaying the set of visual representations of the data set on the display based the visual representation recommendation, and the change in the selected variables, selected abstraction level, the selected visual feature, or the selected views.

Data visualization device and method

An apparatus or method determines a content of the one or more elements of a solid matrix by scanning the solid matrix using a PXRF spectrometer and a color sensor, receiving a PXRF spectra from the PXRF spectrometer and a numerical color data from the color sensor, extracting a value for each of the one or more elements the PXRF spectra, determining the content of the one or more elements of the solid matrix using one or more processors and a predictive model that relates the value of each of the one or more elements and the numerical color data to the content of the one or more elements of the solid matrix, and providing the content of the one or more elements of the solid matrix to one or more input/output interfaces.

Enhanced chemical characterization of solid matrices using x-ray fluorescence and optical color reflectance

An apparatus or method determines an elemental composition of a sample by scanning a sample using a PXRF spectrometer, receiving a PXRF spectra from the PXRF spectrometer, baseline correcting and smoothing the received PXRF spectra, extracting a K&#x3b1; emission line of one or more elements from the baseline corrected and smoothed PXRF spectra from the PXRF spectrometer, determining the elemental composition of the sample using a predictive model that relates the K&#x3b1; emission line of the one or more elements to the elemental composition of the sample, and providing the elemental composition of the sample to the one or more input/output interfaces.

Portable apparatus for determining an elemental composition of a sample

An apparatus or method determines a salinity or metal content a liquid sample by scanning the liquid sample using a PXRF spectrometer, receiving a PXRF spectra from the PXRF spectrometer, baseline correcting and smoothing the received PXRF spectra, extracting a K&#x3b1; emission line of one or more elements from the baseline corrected and smoothed PXRF spectra using only one beam from the PXRF spectrometer, determining the salinity or the metal content of the liquid sample using the one or more processors and a predictive model that relates the K&#x3b1; emission line of the one or more elements to the salinity or the metal content of the liquid sample, and providing the salinity or the metal content of the liquid sample to the one or more input/output interfaces.

Portable apparatus for liquid chemical characterization

The present invention determines one or more properties of a soil sample by scanning a soil sample using a visible near infrared diffuse reflectance (VisNIR) spectroradiometer, scanning the soil sample using a x-ray fluorescence (PXRF) spectrometer, receiving a diffuse reflectance spectra from the VisNIR spectroradiometer and an elemental data from the PXRF spectrometer, determining one or more properties of the soil sample using one or more processors and a predictive model that relates the diffuse reflectance spectra and the elemental data to the one or more properties, and providing the one or more properties of the soil sample to one or more input/output interface.
