Olympus Innov-X Knows Elemental Analysis

Our high-precision analyzers dramatically reduce testing times allowing hundreds more tests per day with significantly higher confidence in site surveys. Our portable XRF analyzers measure 25+ elements per test, from Mg (12) to U (92), PPM levels to 100%.

Three-Beam Settings

Three selectable beam settings are available for varying measurement objectives. A single-incident beam setting can be used for ultra-fast site screening with solid LOD performance across the periodic table. A single-incident beam setting can also be used for exceptional LOD performance for a group of elements such as heavy metals, transition metals & light elements, or to focus in on a particular element of interest such as Cr, Cd, Ni or Cu. And, for more involved analyses, multi-incident beam settings can be used to fully optimize measurements for exceptional LOD performance across the full elemental range or for user selectable elements. You have the ability to choose for your measurement objectives.

Optimized Three Beam Settings: LODs depend on matrix, sample preparation, presentation and measurement time.

Research and development software screen

DELTA handheld XRF analyzers are used extensively by the commercial sector for fast and accurate answers that give an immediate return on investment, maintain quality of incoming and outgoing materials, and help meet regulatory health and well-being requirements. Handheld XRF is also used in the interest of expanding the human knowledge base and satisfying curiosity. On occasion, these discoveries even turn into viable commercial applications.The only real limit to the use of handheld XRF in Research & Discovery is the imagination. Handheld XRF is uniquely positioned to explore the world and beyond. If fast and simple in-situ elemental analysis will enhance your research or teaching experience, contact us to find out how you can get a handheld XRF of your own.


Olympus Innov-X handheld XRF for field archaeometry. 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.

Cultural Heritage

Conservation and restoration of cultural heritage objects pose challenges on many fronts. Whether the need is 

Traditional Native American headwareto 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.


Olympus Innov-X analyzer measuring for field archaeology.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.

Public Health

Individuals tending to cropsGlobal 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.
