DELTA Environmental Handheld XRF Analyzers test for dangerously high levels of RCRA, Priority Pollutant and Hazardous Metals in seconds. HHXRF is used for soils and sediments according to EPA 6200, ISO/DIS13196, and other SOPs, filters per NIOSH or OSHA methods, screening surfaces and measuring dust wipes for Pb, Cd, Cr, As, Hg and more.

Environmental Inspections DELTA Analyzer Provides Fast, Decisive Results


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.

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.

The DELTA is ideal for measuring priority pollutants Ag, As, Cd, Cr, Cu, Hg, Ni, Pb, Se, Tl, Zn, and RCRA Metals Ag, As, Ba, Cd, Cr, Hg, Pb, and Se.

The big picture is seen with GPS-XRF metal-concentration contour mapping. The unique DELTA Xplorer Option wirelessly integrates GPS coordinates with the DELTA XRF results. Coupled with a measurement control Field Soil stick, the DELTA XRF is a very cost-effective tool available for large sites, and enables large, inexpensive data sets to be generated very quickly.

The full power of the DELTA series is unleashed with the DELTA 50 kV unit for the ultimate in speed, sensitivity and low limits of detection for challenging elements such as Ag, Cd, Sn, Ba, and Sb.

The DELTA Handheld XRF for Environmental Inspection

The DELTA Environmental X-ray fluorescence spectrometer is a powerful handheld XRF designed for complete environmental investigations of metal contaminants in soils, sediments, fluids, dust wipes, and filters. This high-power, high-performance, field-ruggedized handheld XRF with hotswappable batteries offers you 24/7 heavy-duty operation anywhere you use it.

The Powerful Handheld XRF that Can Be Taken Anywhere

Get Fast Results for Immediate Action

DELTA Handheld XRFThe DELTA can be used to identify and quantify lead (Pb), arsenic (As), mercury (Hg), chromium (Cr), and other contaminant metals quickly and accurately. Take it anywhere to get fast results for site characterizations, property evaluations, contamination tracking, hazardous waste screening, remediation monitoring, and regulatory compliance. Requiring little to no sample preparation, the DELTA Environmental Analyzer is the ultimate tool for screening large sites and for analyzing samples such as bagged soil, sediments, cores, fluids, dust wipes, surfaces and filters.

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.
