Small Tabletop Micro-XRF Spectrometer

Designed for Jewelry Analysis in Narrow Space Situations

The M1 ORA is the ideal instrument for non-destructive analysis of jewelry, precious metals or coins – especially in situations where space is limited.

Ease-of-use, a small footprint and rugged design combined with excellent analytical results are its main features.

Persons who have received only introductory training – for instance personnel in a jewelry shop – will be able to generate reliable information on precious metal content within minutes.


Excellent analytical accuracy

The M1 ORA works in ambient air, can therefore analyze elements from titanium (Z=22) upwards and is well suited for the analysis of jewelry alloys. Samples are excited by a low power micro-focus X-ray tube. Radiation is detected by a large sensitive area proportional counter. This results in the instrument's excellent analytical accuracy, its low limits of detection and in the ability to analyze every element with a concentration higher that 0.5 %.

High spatial resolution

The measurement is contactless and non-destructive. The excitation from above with a spot size down to 0.3 mm allows exact pinpointing of the desired area for analysis, even on most intricate pieces of jewelry. Specimens may be as large as 100x100x100 mm3. Positioning is aided by a built-in video microscope with cross-hair function. For additional user comfort the manual scissor stage can be replaced with an optional motorized z-stage.

Easy-to-use software

The analysis software XSpect allows to identify and determine concentrations even of elements one would not expect to find in a jewelry alloy. The software uses state-of-the-art standardless and standard-based quantification models which provide accurate analysis with less than 0.2 % (weight) standard deviation. The software features:

  • Instrument control, data acquisition and management
  • Element peak identification
  • Quantitative composition analysis – standardless and standard-based
  • Report generation
