Bruker Micro XRF

Bruker M4 TORNADO Micro-XRF

Analyse Composition and Element Distribution

The Bruker M4 TORNADO rapidly measures composition and element distribution, generating a wealth of information. The micro-XRF instrument of choice for research in materials science, forensics, archeometry and microelectronics, including catalysis, failure analysis, corrosion research and failure analysis. Perform material testing, quality control, layer system analysis, toxic element screening and many other analytical tasks.

Analyse a Wide Range of Samples:

  • Virtually any kind of inorganic, organic or even liquid sample
  • 600mm x 350mm x 260mm sample chamber for large samples and weights up to 5kg
  • Even and irregular shapes

A large vacuum sample chamber supports light element detection. Spot sizes down to 25 µm provide excellent spatial resolution. Larger spot sizes up to 200 µm are now also available with the new FlexiSpot feature, for analysing inhomogenous materials. Read a lab report about the M4 TORNADO’s performance in important measurement parameters.

Customise the M4 TORNADO for extended measurement ranges and even faster analysis speeds. Adding a second tube with a different target and collimator enhances flexibility. For the fastest analysis speeds, add a second SD detector.

Corrosion analysis


Low-alloy steel is highly sensitive to corrosion. Parts and structures made of this steel are often protected by a Zn or a ZnAl coating. Analyse treated steel samples and examine elemental distribution for a better understanding of corrosion processes and how to reduce corrosion.

Solar cells & thin films analysis

Solar Cells

Measure thin film solar cells both in air and under vacuum. Micro XRF can be used in-line during manufacturing as well as for final product testing.

Archaeological analysis

Forensics and Archeometry

Examine layer systems such as paint, extremely small material fragments and gunshot residues. The M4 TORNADO is also ideal for non-destructive analysis of documents and small works of art, for example for authentication.

Small Particle Analysis

Small Particles

Analyse the chemical composition of small particles to determine their origin. For example, analyse wear debris in engine oil to highlight components causing abrasion. Particles in plastics influence the performance of the material and are typically caused by contamination, from the manufacturing machinery or environment.

Distribution analysis of electronic components

RoHS (Restriction of the Use of Hazardous Substances)

Detect substances imposing environmental and health hazards. Determine compliance with the Restriction of the Use of Hazardous Substances regulation. The M4 TORNADO can determine heavy metal and other harmful element content, even in the ppm range. Qualitative analysis of single points and examination of element distributions for various sample types, including electronic components, toys and consumer products. The high excitation efficiency of the M4 TORNADO quickly screens and detects even the smallest traces.

Bioscience analysis


Examine the metabolism of biological samples for valuable information about environmental conditions, health and diseases. Analyse the distribution of essential elements in plants and in animal organs with high spatial resolution and sensitivity. Fast data acquisition enables sensitive samples to be screened without causing damage.

Analysis of geological samples


The large sample stage of the M4 TORNADO is perfect for analysing geological samples. Phase analyses and searches for trace elements can be performed easily, to study geological processes such as rock formation or to assess ores for mineral content. The software features a wealth of useful options for analysis and data representation.

Inhomogenous Samples

Inhomogenous Samples

The new FlexiSpot feature adds the option of a larger spot size, up to 200 µm, for more precise quantification of inhomogenous and uneven samples, including irregular shapes, powders and granular samples. Data is collected from a larger area, still at high resolution, for more a more accurate representation of the material’s composition.
