Soil testing with the world’s most powerful handheld XRF

SciAps X-555 features the world’s only 55 kV tube, yielding superior limits of detection and precision for the subset of RCRA and Priority Pollutant metals cadmium (Cd), Barium (Ba), Tin (Sn), Antimony (Sb), and silver (Ag).

Up to three automated beam settings, designed for optimal performance across the entire periodic table from Mg to U. The high voltage beam operates at 55 kV with appropriate filtering to optimize sensitivity to cadmium and other metals in that atomic number range. Lower beam settings provide analysis for the remaining RCRA and Priority Pollutant metals including Pb, As, Hg, Cr, and others.

EPA Method SW-846 Test Method 6200: Field Portable X-ray Fluorescence Spectrometry for the Determination of Elemental Concentrations in Soil and Sediment

The 55 kV X-ray tube allows for extra low detection limits on key elements like Ag, Cd, Sn, Sb and Ba, making it especially well suited for RCRA applications and EPA Method 6200.

The X-555 and other SciAps XRF analyzers meet the test method for both in-situ soil testing as well as bagged and prepared/cupped XRF samples. The method provides a standard operating procedure including analyzer calibration checks and sample preparation guidelines. A copy of the method may be downloaded here:

What about beryllium?

Beryllium is included in the EPA Priority Pollutant Metals. For operators that require beryllium (Be) analysis, SciAps offers a dedicated LIBS (laser-induced breakdown spectroscopy) analyzer, the Z-901 Be. Portable XRF cannot measure elements lighter than magnesium in the field, whereas LIBS technology excels at Be measurement, and in fact the SciAps LIBS can measure even hydrogen.

Get it all in One Box

The One Box for Environmental combines the performance-leading X-555 for the 8 RCRA metals and 13 of the 14 Priority Pollutant metals, along with the Z-901 Be, a dedicated beryllium analyzer. This pair provides optimal performance across all regulated metals with true field portability. Analyze soils, sediments, liquids, filter, and wipe media.

Test Station / Field Lab

For users who want to test bagged samples, liquid samples, or prepare soil or sediments and place them into XRF cups for analysis, we recommend using the SciAps Test Station, a compact, robust platform with interlocked lid. The XRF points up into the stand, where the analyzer will not fire unless the lid is fully closed. When using the system in this fashion, X-ray radiation is not detectable above typical background rates, making this method a closed-beam system.

Other XRF models

SciAps offers a range of price/performance options for our XRF environmental analyzers. For more industry-typical analysis of Cd, Ba, and the other metals noted above, the X-505 offers less expensive high performance options. For users only interested in a few elements in soil, such as lead and arsenic, SciAps can configure the X-505 for single-beam, optimized analysis at greater savings. Please contact us with your specific requirements.

Industrial Lead Paint App

Any of SciAps X-500 series XRF units may optionally be equipped with Industrial Lead Paint app, a fast screening method for lead paint in industrial settings as part of OSHA compliance.

OSHA regulates worker lead exposure via airborne lead that is generated from various destructive activities such as cutting, torching, welding, etc. on metal surfaces that may contain lead-based paint. While there is no defined threshold lead level in the paint that may be used uniformly to declare that no airborne exposure may occur, a large body of experimental testing by various facilities shows that if there’s no detectable lead in paint, then, for nearly all activities, no airborne lead exposure will occur. These data are obtained by measuring the lead in paint, performing the activity with worker air monitoring in place, and then analyzing the air filters from the cassettes for lead content. Once background data has been obtained that shows no airborne lead exposures, the burden of ongoing monitoring and excessive PPE is alleviated.

At this time, the SciAps XRF units cannot be used for residential, school, or day care lead-based paint testing. To perform this type of testing, the device must go through EPA testing and be issued an EPA Performance Characteristic Sheet (PCS). The SciAps XRF device does not have a PCS.
