DELTA Environmental Complies with Global Methods

Olympus strives to play an integral role in society by putting our technologies to work to help develop a better future. We do this by taking up the challenge of making the hidden visible. Pollutant metals are usually hidden from view, but with Olympus X-ray fluorescence technology, we make them visible in the global effort to help make the world a cleaner, greener place. Portable XRF measurements are made to help ensure that dangerous levels of toxic metals are not present in the land, water or air where we live, work, play, cultivate food or obtain water.

US EPA 6200
On-Site Screening of Heavy Metals in Soil and Sediments

Method 6200 was first developed in the mid-1990s and is still strong worldwide for in-situ (handheld) and intrusive (portable) XRF methods. It provides basic portable XRF quality assurance methods including calibration verification, determination of instrument precision, accuracy and LODs to create a standard field XRF method. Following the method decreases sampling error by increasing the number and quality of samples tested to improve overall data quality. It suggests XRF testing methods include in-situ soil, bagged soil, and fully prepped soil samples. Method 6200 does recommend confirmation of 5-10% of samples tested by portable XRF with an EPA Lab method. Overall, it recommends XRF as a fast, powerful, cost-effective technology for site characterization with the analytical benefits of more and better field testing to improve site understanding.

EPA TCLP HAZMAT Classification
The Rule of 20 for Cost Savings on 8 TCLP RCRA Metals

The DELTA can be used to follow the “Rule of 20″ for cost savings in relation to the TCLP HAZMAT Classification Process. If results are significantly less than the TCLP regulatory limit, or are less than 20 times the TCLP regulatory limit, time-consuming and costly TCLP/Lab testing can be avoided.

Residential and Industrial Hygiene Monitoring of Pb

The DELTA Environmental Analyzer complies with EPA, NIOSH, and OSHA XRF methods of monitoring Pb on surfaces, in paint, dust, and flakes, and on industrial airborne particle monitors and filters. These methods help protect the health of families and industrial process workers.

ISO/DIS 13196
Soil Quality Screening

This draft describes XRF as a quick method for on-site screening of heavy metals and for the determination of total elemental compositions of soil samples. It is similar to EPA Method 6200, but it does not specify elements, it encourages the objectives of the project to dictate the elements. It calls for reasonable sample preparation and quality control for portable and handheld X-ray fluorescence measurements of heavy metals in soil.

The analysis of soil for contaminant metals is the most common environmental application of handheld X-ray fluorescence spectrometry. Simple screening for toxic metals is performed by placing the analyzer directly on the soil, in-situ. The DELTA provides ease in detecting metals for site characterization, contamination tracking, remediation monitoring, property evaluations, extreme-weather debris migration studies, construction and demolition waste sorting, industrial or mining community perimeter checks, agriculture soil inspections, and hazardous waste screening for disposal classification. Quantitative measurements of the metals are based on robust preprogrammed calibration methods that may be refined by the user.


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.

Surfaces, Dust Wipes, and Filters

The DELTA is used to measure Pb on surfaces and in dust, paint chips, and flakes. The DELTA can also be used to check filters for airborne metals from welding, construction, mining, manufacturing, and paint removal activities.

Liquids and Fluids

The DELTA can be used to inspect runoff streams, industrialwaste fluids, HAZMAT and oil spills for metal contaminants before they seep into the soil, or reach ground water and drinking water sources.

Community & Residential Development

The DELTA is ideal for immediate identification of heavy metals in soil at low PPM levels. This is necessary to ensure safety prior to developing or renovating schools, community centers, residences and play & sports grounds. This is of particular importance when developing these properties on former landfills, industrial sites, orchards, animal farms, Brownfields or anywhere that toxic metals are likely to be found in large quantities. And, when older homes or buildings are being redeveloped, restored or painted, the DELTA is ideal for quickly identifying lead (Pb) in soils, on surfaces and in lead based paint (LBP) to ensure the safety of the project.

Dangerously High Levels of Toxic Metals in Developing Countries

Dangerously high levels of 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 and living conditions.

Agronomy & Peri-Urban Farming

The safety of food sources is becoming increasingly important as the human population expands. With this growing demand, peri-urban farming and precision agriculture are becoming more commonplace. However, farming in areas adjacent to industrial and other urban facilities introduces the possibility of food crops grown in soil or irrigated with water with elevated levels of As, Hg, Cd, Cr & Pb. And, urban sprawl into areas once heavily farmed with unregulated pesticides, may introduce As and Pb to these new community gardens. The DELTA handheld XRF allows for rapid determination of these toxic metals as well as of nutrients and fertilizers, such as Ca, Mg, P & K. The DELTA XPLORER is ideal for precision agriculture as it allows for high intensity soil analysis in the field with results obtained and spatially modeled on-site.

Hazardous Waste Screening & Sustainable Industry

Most industries are now under pressure to follow a sustainable development plan to help minimize the environmental and health impact of their manufacturing and packaging processes. Handheld XRF systems are used on site by industry, engineering firms and regulators to ensure that any metal contamination is quickly identified and that remediation steps are working effectively.

Regulatory Compliance

Portable XRF is a well documented and valuable tool for both private and government regulatory driven analysis of heavy and priority pollutant metals in residential soils. This non-destructive method with its quick analysis time and high quality measurement capability make it ideal for field assessments, particularly of large areas. In fact, US EPA Method 6200 and ISO/DIS 13196 encourage portable XRF screening for high density, high volume sampling to correctly characterize a site.

Scrap Recycling, Metal, Glass, & Plastic

Scrap refiners and recyclers need fast and accurate materials analysis and identification. Our portable and automated XRF analyzers sort scrap metal, plastics, and glass and offer precise, dependable compositional measurements faster than ever before, even for aluminums and light alloys.


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.

Forensic Anthropology

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.
