Bruker Nano GmbH - M4 TORNADO - Micro-XRF Spectrometer

2D µ-XRF with Ultimate Speed and Accuracy

The Instrument of Choice for Highly Sensitive and Non-Destructive Element Analysis

The M4 TORNADO is the tool for sample characterization using small-spot Micro X-ray Fluorescence (µ-XRF) analysis. Optimized for analysis speed and without compromising accuracy it measures a wide range of samples, whether small or large, even or irregularly shaped and generates a wealth of information on composition and element distribution.

Equipped with a large high-speed stage it supports 2D analysis of virtually any kind of inorganic, organic and even of liquid sample.

Providing spot sizes down to 25 µm (for Mo Kα adiation), excellent spatial resolution is warranted. The proven ESPRIT analysis software provides a flexible measurement setup and a variety of evaluation and processing tools. A large vacuum sample chamber supports light element detection.

The instrument can be customized to provide extended measurement ranges or even higher analysis speed: flexibility can be enhanced through installation of a second tube with a different target and a collimator. An optional second SD detector increases speed even further.

The M4 TORNADO combines state-of-the-art X-ray generation and detection technology with an unique usability concept, resulting in a powerful, yet easy-to-use instrument for non-destructive element analysis:

• 25 µm Spotsize
  Polycapillary X-ray optics focus the tube radiation to smallest areas, generating spots of highest radiation brilliance on the sample surface down to 25 µm diameter for Mo K radiation. 
• XFlash Technology
  The XFlash® silicon drift X-ray detector technology is the key to the instrument's outstanding performance, providing excellent energy resolution at highest count rates.
  
• Dual Detector
  The standard version of the M4 TORNADO is equipped with a single high performance XFlash® detector. Optionally it can be fitted with a second detector for even higher speed and additional analytical possibilities.
  
• Dual Tube Excitation
  The M4 TORNADO is equipped with a single rhodium target X-ray tube. Additional analytical flexibility can be attained by adding a second tube with a different target material or a collimator instead of polycapillary optics.
  
• TurboSpeed Stage
  The TurboSpeed X-Y-Z stage supports analysis "on the fly". Defining areas for measurement is aided by a dual video microscope with variable magnifications. An additional fish-eye camera provides a view of the sample chamber.
• EasyLoad Chamber
  The motorized sample chamber door opens at a push of a button. The stage is at the same time automatically moved to the front where samples can be exchanged easily without having to reach inside the chamber.
• M-Quant
  The powerful ESPRIT software of the M4 TORNADO uses an advanced Fundamental Parameter based approach for quantification.
