The application of physics and chemistry to investigate archaeological and historical objects benefits tremendously from handheld XRF. Most governments will not allow investigators to remove materials from their original setting; and, sometimes their removal or even disturbance can destroy the value of the object. In-situ, non-destructive handheld XRF analysis provides valuable information for the assessment of a site - where to dig next, the relationships among loci, the homogeneity of materials, the authenticity of a cave or fresco painting and more. Combining GPS with handheld XRF in the field for instant metal mapping takes archaeological field research to an entirely new level.
Conservation and restoration of cultural heritage objects pose challenges on many fronts. Whether the need is to identify the authenticity of an object or to determine the correct restoration materials, handheld XRF is an ideal tool to aid the analyst without damaging the object. Handheld XRF is used to help reproduce glaze colors on historical buildings with modern non-toxic material. It is used to help identify and restore inks on ancient manuscripts. Handheld XRF is also used to identify and/or repair alloys of jewelry, swords, sculpture, and even historical submarines. It is also used to identify arsenic or lead residue left by older, toxic preservatives on historical objects typically of natural material origin, such as feathers or skins. Many museums and cultural heritage institutes use handheld XRF on a regular basis.
The field of geo-science includes discovery, safe use, and sustainablity of valuable land resources. This includes the safety of food sources with the growing demand for peri-urban farming and precision agriculture. The DELTA handheld XRF allows for rapid determination of toxic metals introduced to the soil and water as herbicides or pesticides, such as As and Pb, as well as correct placement of nutrients and fertilizers, such as Ca, Mg, P & K. It also includes the use of handheld XRF by geologists to determine the history of soil layers indicating events that have occurred throughout geological time. The DELTA XPLORER is ideal for this research as it allows for high intensity soil analysis in the field with results obtained and spatially modeled on-site.
Grave digging elicits numerous connotations, usually horror film in nature. But, forensic anthropologists actually study graves and their inhabitants to learn the origin of those buried, how they perished, and sometimes if the bodies were moved. Additionally, handheld XRF is utilized by forensic odontologists to assist in victim identification by analyzing dental restorative resin materials. Acting like a fingerprint, even if the body has been burned, this method has helped to identify victims of extreme incineration cases.
Global advocacy groups work to uncover situations and materials that pose dangers to public health and well being and to determine a course of corrective action. For instance, high levels of lead (Pb), arsenic (As), mercury (Hg), chromium (Cr), cadmium (Cd) and other toxic metals can be found in the domicile and play areas of peoples in developing countries where the knowledge of their danger are not yet known or where regulations are simply not yet feasible. Handheld XRF analyzers are used to quickly ascertain the presence and quantity of these contaminants. This allows world health advocacy groups to determine a course of corrective action to help developing countries prosper with local resources and with safe working practices.
The energies (keV) at which the peaks appear identify the elements present in a material. The intensities (Counts/s) of peaks correlate with the concentrations of the elements present in the materials.
The DELTA provides qualitative and semi-quantitative elemental information to guide research and identification of unknown or complex materials. It provides results fast and relevant enough to keep students engaged in classroom learning. It is sophisticated enough to provide directional results for applicable science-based projects in the field.
Close Up Analysis
This DELTA can be equipped with a camera/collimator to provide the ability to focus in on a specific area of an object, take a measurement and save the spectra, composition, and digital image of the analysis area all at once. This is an ideal tool for archaeology, conservation and forensic science.
DELTA handheld XRF screens precious metals
Nondestructive Handheld XRF can be used on a variety of materials including gold, silver, platinum, copper, brass, pewter, ceramics, mortar, glass, wood, paintings, fabrics, canvas, bone, rocks, ores, soil, slurries and fluids.
The DELTA comes with factory calibrations for multiple applications. Soil Mode utilizes Compton Normalization for PPM to 3% levels of elements in light matrices, such as soil, liquids, mortar, bone, wood, fabric, or canvas. Mining Plus Mode utilizes Fundamental Parameters (FP) for elements at levels greater than 3% in light or complex matrices, such as rich soils, slurries, rocks, and ores. GeoChem Mode combines the low concentration capability of Soil Mode with the accurate handling of percent level concentrations of Mining Plus Mode. Alloy Plus Mode with Precious Metals utilizes FP for a wide range of elemental concentrations in metal or alloy matrices.
Empirical Calibration Mode is used to set-up calibration models with a series of user-specific certified standards. Linear or quadratic fits are available and results can be displayed in selectable units - %, ppm, μg/cm2 or alternate units. Once these calibration models have been created, named and stored, they can be transferred to the DELTA for use in the field.
DELTA PC software provides additional capabilities for off line data analysis including periodic table selectable peak identification, concentration results, images collected, and spectral overlay of samples sets. It can also be utilized to remotely control the DELTA in a closed-beam portable workstation.
The DELTA can be equipped with the Xplorer package to provide seamless integration of XRF-GPS-GIS data for metal mapping. The ability to map, visualize, assess, question and take immediate action from real time results has genuinely changed field research capabilities. The Xplorer package is ideal for investigating archaeological dig sites, public parks, farms, or even burial grounds. The holster, soil foot, and soil stick are great convenience accessories for metal concentration contour mapping of large sites.
