PXRF Calibrations

Rhizoterra builds custom calibrations for Bruker Portable Handheld Laboratory X-Ray Fluorescence (XRF) Spectrometers.  This includes Tracer SD-III, Tracer SD-IV, and the Tracer 5i series. Our calibrations are suitable for agriculture, horticulture, food processing and fertilizer industry analyses of atomic elements from sodium (Na) to uranium (U).

Helium (He) or a vacuum is used to increase the ability of the instrument to detect photons from low atomic weight elements such as sodium (Na), magnesium (Mg), and aluminum (Al) and we offer calibrations using both helium (He) and vacuum. Elements with less atomic weight than sodium (Na) are not detected by these instruments.  We also offer a calibration for dried plant materials with higher concentrations of chlorine (Cl).

We are currently developing a number of other calibrations and encourage you to contact us Avril at avril@rhizoterra.com , if you are trying to quantitatively analyze materials other than what is listed below.

Every instrument has to be custom calibrated because all Bruker PXRF laboratory instruments are custom built and the rhodium-based tubes inside each instrument are unique.

Rhizoterra’s Current list of Calibrations:

All calibrations are offered for Tracer SD-III, Tracer SD-IV, and Tracer 5i systems.  Rhizoterra uses helium (He) for the analysis of sodium (Na) through zinc (Zn) in the following matrices:

  • Soils and Composts
  • Dry ground plant material
  • Dry ground food grains
  • Water-like liquids (example aqueous fertilizers, wine, sap, and water)

Calibrations for heavy and/or toxic element analyses (calcium (Ca) through uranium (U)) are also available for the same matrices.

Our calibrations are all designed to report in parts per million (ppm), and we remind you that with XRF you are measuring total amounts of each element.

Rhizoterra Laboratory PXRF Accessories:

Helium Flow Control System: controls the flow of helium from a portable balloon tank to the XRF/PXRF, helium must be used with all helium calibrations.

Training and custom applications:

All calibrations are fully supported by Rhizoterra.  We can work with you to adapt PXRF to your analytical applications.

We offer onsite or online training workshops so you can optimize the use of your Tracer to your unique application.

Got a Tracer SD-III or SD-IV and are using it for art, anthropology or archeology studies why not analyze soils and clays as well using our custom soil calibrations.
