Toxic Metals Monitoring with Handheld XRF Analyzers

Portable XRF (PXRF) Analyzers are fast, non-destructive tools used to analyze water, soil and crops for heavy metals; and, they are incorporated in regulatory methods to screen soils.

Although marijuana is not yet regulated for toxic metal content, PXRF is a fast method for screening its plants and processed goods for dangerous levels of these metals.

Handheld XRF (HH-XRF) is also used to monitor high metal levels  in water and soil caused by climate change, anthropogenic pollution and catastrophic geological or extreme weather events.

Solutions for Sustainable & Healthy Soil, Crops & Food

  • Monitor heavy metals (Pb, As, Hg and more) in-situ and in real time

  • Determine toxic metal concentrations in water, soil, sediments and crops with matrix-matched standards

  • Profile the effectiveness of phytoremediation by characterizing toxic metal uptake in soil remediation plants such as Indian Mustard (for Cd, Pb, Se, Zn, Hg, Cu, 137Cs), White Willow (for Cd, Ni, Pb), Sunflower (for Pb, Zn), Hemp (Cd, Pb, Ni 137Cs) or Ladder Brake (for As)
