In Situ Testing Using NITON's XRF Analysers

In situ testing provides rapid, quantitative screening measurements to rapidly profile contaminant levels and determine remediation boundaries with surgical precision.

NITON XLi/XLt 700 Series multi-element analyzers are designed for both in situ and ex situ soil testing. Choose the analysis that best suits your applications and data quality objectives. For in situ analysis, place the XLi/XLt 700 Series directly on the ground, or test bagged soil samples. Since contamination patterns tend to be heterogeneous, the large number of data points produced using in situ testing typically provides a faster, more precise, and far more cost-effective way of delineating contamination patterns.

In situ testing with the XLi/XLt 700 Series is in full compliance with EPA Method 6200, Field Portable XRF Spectrometry for the Determination of Elemental Concentrations in Soils and Sediments. In situ testing lets you test many locations in a short time and is ideal for:

  • » Rapid site-profiling
  • » Locating sources of contamination
  • » Monitoring and fine-tuning remediation efforts on-the-spot


XLi/XLt 700 Series soil testing is non-destructive, so accredited laboratories can reanalyze all prepared samples to confirm results.

For in situ soil testing, the XLi/XLt 700 Series never needs site-specific calibrations. Sophisticated software corrects automatically for variations in soil-sample chemistry and density.
