BRuker M1 Mistral





A Compact Multi-Purpose Benchtop micro-XRF Spectrometer

Key factors

  • Flexible instrument
  • Easy to operate
  • User-friendly touch screen interface
  • Access to raw data

M1 MISTRAL is a compact benchtop energy dispersive micro-XRF analyzer for multi-purpose use.  Easy to operate and designed for fast and cost-efficient operation in an industrial environment, M1 MISTRAL provides accurate information on the elemental composition and layer thickness of materials such as precious metal alloys as well as for multi-layer structures.

Bulk and coatings are analyzed according to ASTM standard B568 and to European norm ISO 3497. High accuracy can be achieved in the analysis of electroless deposited nickel phosphate (NiP) coatings with excitation through a Rh target.

The exact composition of all jewelry alloys, platinum group metals, or silver can be determined in a fraction of a minute. Results can be output either in weight-% or in carat.

The analysis can be performed standardless or standard-based to reach even higher levels of accuracy. A great variaty of calibrations is available for each application.

From positioning the sample to printing the results in a report – the full workflow is integrated in the software. At the same time full transperency is guaranteed with the open access to the raw data.

Benefits of the M1 MISTRAL

A wide variety of elements can be measured non destructively. No sample preparation is required. Even complex analytical tasks can be automated with the programmable XYZ stage and started with a single mouse click. Ultra-fast detection systems provide quick results.

The M1 MISTRAL comes with a large area silicon drift detector (SDD) with superior count rate performance and energy resolution to drive detection limits down to the ppm level. High performance detector, digital pulse processing and optimized geometrical conditions result in a highly efficient X-ray detection and therefore fast and accurate analysis results.

The easy-to-use and maintenance-free design of the M1 MISTRAL and the powerful analytical software suite permit operation even by personnel who have received only brief training. No consumables or gases are required. Sturdy construction ensures highest stability and maintenance-free operation.

Great Flexibility and a Wide Range of Applications
Printed circuit board
Coating and Layer Anaysis
Metal coatings are essential to many industrial sectors by providing enhanced surface properties to a wide variety of products. The quality control of composition and thickness of coatings is critical to ensure the correct coating properties and durability.
Car gear box
Electroless Nickel Coatings
Electroless nickel plating (ENP) is an auto-catalytic chemical process used to deposit a layer of nickel-phosphorus (Ni-P) alloy coating on a substrate. One of the key benefits of the nickel-phosphorus coating is that it provides a very consistent thickness that isn’t dependent on part geometry.
Home appliances
Restricted Materials Screening
With the increasing presence of electronic devices, electronic waste is also being produced faster than ever before. In recent years the EU and other countries have established a multiple regulations to promote recycling of e-waste and reduce the health and environmental risks associated with the increase in e-waste production.
