xplorex supplies X-ray systems for both elemental analysis by XRF and structure analysis X-ray diffraction (XRD). Although not limited to, our X-ray diffractometer is mainly used in Geological exploration, where in-field analysis is of paramount importance.

Our portable XRD equipment helps reducing transport- and laboratory costs significantly.



With the PLANET we have built a portable powder diffractometer with sufficient attainable resolution to identify even the most complex mixtures of minerals

On-site XRD analysis for Geology and Mineralogy

One of the most important applications of X-ray diffraction is  the identification of the phases in soil samples taken during an exploration. Among others the results of these analyses help you decide whether it is worthwhile to return to the site for further investigation.

What if these analyses could be done already in the field?

  • Save significantly on lead time and cost
  • Allow for pre-selection of sample. Only the most interesting ones need to be sent to a laboratory.
  • Immediately yield the results where and when you need then

Therefore, we developed the PLANET!

  • A portable diffractometer designed to meet all the specifications needed for complex phase identifications
  • Works on a set of Li-ion batteries with constant performance of minimum 4 hours  (20Ah at 24 V)
  • 30W X-ray tube with Cu-anode. Other materials on request
  • Ultra-sensitive linear detector covering 7° in 2Theta
  • Compact design based on the Seemann-Bohlin focusing geometry

Angular range


The PLANET covers an extraordinary angular range in both incident- and scattering angles, which is unsurpassed by any portable X-ray diffractometer:

  • Angle of incidence range: 6.7° - 45°
  • Scattering angle: 7° to 120° 2Theta

Over the whole range of the measured XRD pattern the peak positions deviate less than 0.02° from the theoretically predicted.

The exceptional resolution of the PLANET is demonstrated below.

The peaks are measured on LaB6 , a well accepted standard to quantify the attainable resolution of a powder diffractometer. Profile fitting of these two peaks shows an FWHM of 0.10° in 2Theta.



To validate the Planet in-field X-ray diffractometer, we took two samples readily at hand to identify the phases therein. Kitchen salt and Calcite. We measured these samples from 23 - 110o 2Theta. We analyzed both X-ray diffraction patterns with the Match! software from Crystal Impact. In both samples the correct phases were identified without the need to apply any restrictions. We just loaded th pattern and the software automatically came up with the correct result.

Anatase in Rutile


One of the classical applications of XRD is the quantitative determination of the amount of anatase in rutile. We received a sampe of Rutile, where the manufacturer claimed it contained 99.9% of Rutile, while the customer measured approximately 95% with his laboratory based diffractometer. With the Planet in-field diffractometer and the Match! software we found an estimated 4.4% of Anatase,using the RIR method.
