Ex-Situ Analysis
Thermo
Scientific NITON® XRF analyzers can be used to test bagged or
prepared samples. Measuring bagged samples roughly
homogenizes the samples, generally making them more
representative of the locations where they were collected.
For true lab-grade analytical data, full sample preparation
(dried, ground, sifted, and cupped) is necessary,
frequently resulting in correlations with lab data with r2
>= 0.98.
Either way, the instrument's portable test stand readily accommodates various
sample types, while permitting viewing and control either directly from the
instrument, or from a connected PC or PDA with the included
NITON Data Transfer (NDT) software.
This robust software eliminates the
need for site-specific calibration standards, while flexible capabilities
permit users to fine-tune calibrations as required to meet data quality
objectives (DQOs).
All measurements are nondestructive. Following standard
protocol, only 5% of all samples are sent to an accredited
laboratory for confirmatory analysis. By screening samples
prior to collection, environmental professionals will
eliminate the testing of high-concentration samples during
confirmatory testing. /p>
