Bruker Micro-XRF

The Bruker M1 MISTRAL is a compact, tabletop micro-XRF analyser for bulk materials, layers and coatings. Analyse a wide range of materials including metals, alloys and multi-layer systems, in electronics, jewellery, RoHS (Restriction of Hazardous Substances), automotives and more.


Flexible sample sizes

Up to 100 x 100 x 100 mm

Wide range of elements

From Z = 22 (titanium) and higher

Sensitive detection

Detection limits down to 0.01%


Fast and easy to use


Samples are simply placed directly on the sample stage, with no preparation necessary. The contactless measurement is taken from above, so irregular shapes, such as finely wrought jewellery and materials of varying thickness can all be analysed easily.

Example Applications

ROHS Compliance Testing

Determination of RoHS Compliance

The high performance version of the M1 MISTRAL can also detect trace elements in light matrices according to RoHS requirements. This enables direct control of hazardous element concentrations in electric and electronic devices.

Coating Analysis by Micro-XRF

Characterisation of Coatings

X-ray fluorescence technology can analyse thin coatings, eg on PCBs, metals or plastics, including both single and multi-layer coatings. Layer thickness and composition are calculated simultaneously, using a standardless fundamental-parameter based method.

Gold purity analysis

Jewellery and Alloy Analysis

The M1 MISTRAL is ideal for the analysis of jewellery, coins and precious metal alloys. The exact composition of jewellery alloys, platinum group metals or silver can be determined in a fraction of a minute. Results can be output either in weight% or Karat. Accuracy is better than 0.2 wt% for main element content in the range of 40 – 100 %.
