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.
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
