EPA Method 6200
The
handheld Thermo Scientific Niton XRF analyzer
allows the operator to analyze all 26 elements listed in the
United States
Environmental Protection Agency (USEPA) Method 6200 in a
single analysis. The instrument is capable of both in situ
analysis, for delineating contamination boundaries, and
intrusive (ex situ) analysis which, with suitable sample
preparation, can provide laboratory-grade results in the
field.
The nondestructive nature of the test also allows the
identical samples to be sent to the laboratory for
confirmatory testing as required (5% of all samples per EPA
6200).
Immediate identification of the elements that are present, including the
8 Resource Conservation and Recovery Act (RCRA) metals, and accurate
determination of the concentration of those elements provide a rapid soil
contamination profile, making it an ideal tool for Brownfield evaluation.
Our analyzer includes a Soil Accessory Kit,
providing everything required to prepare soil samples for ex
situ testing. Drying, grinding, and sieving of soil material
yields a homogenous sample that allows the instrument to
give more accurate results in better agreement with
lab-reported values.
The proprietary software algorithms automatically correct
for interferences and also for variations in sample density.
For those rare sample types in atypical soils, the
instrument may be adjusted with site-specific samples to
provide a more optimum calibration.
