Spectroscopy
The Laboratory of X-ray Micro and Nano Computed Tomography of Advanced Instrumentation and Methods for Materials Characterisation research group is a part of the Industrial Cybernetics, Instrumentation, and Systems Integration Research Programme in the Central European Institute of Technology (CEITEC), located at Brno University of Technology.
The CT Lab combines the development of tomographic methods including the software development and their applications in various scientific and engineering fields (e.g., biology, geology, archaeology, CT metrology, industry). It offers non-destructive testing of final and developing products, characterisation of internal structure of materials, volume quantification, inspection of dimensions and geometric tolerances, bulk density, particle distribution and orientation or porosity.
The Laboratory of Laser Spectroscopy is a part of the CEITEC Nano Research Infrastructure. It belongs to the research group of Advanced Instrumentation and Methods for Materials Characterisation (RG1-6) at the Central European Institute of Technology, Brno University of Technology (CEITEC BUT).
The LIBS Lab follows up with the 20 years of tradition in interdisciplinary research and development, combining engineering, analytical chemistry, statistics, and now even biology, with a high-end state-of-the-art instrumentation. The primary research aims at providing the elemental analysis of investigated samples. This elemental analysis is mainly used in the elemental mapping, which enables a valuable perspective in the understanding of the material itself, ranging from geological to biological samples.
Equipment CTLab
Versatile CT system with a walk-in air-conditioned protection cabinet equipped with micro- and nano-focus X-ray sources and a large 4000 x 4000 px detector and a granite-based 7-axis manipulator for long-term stability and the highest precision. A suitable system for large-scale samples (maximum object size Ø 500 × 800 mm). The newest addition, the In-situ box (by CactuX s.r.o.) allows for the simulation of real-life conditions during CT analysis, offering temperature control (-30 °C to +60 °C), a charging/discharging function to investigate batteries (up to 30 A), and a power supply function (up to 30 A/60 V) with the sample area of 35 mm x 65 mm.
Industrial CT with a powerful microfocus tube, air-bearings, a fixed detector-source distance for a better metrological performance. Excellent device for structural analysis of high-density samples and larger pieces of rocks (e.g. meteorites).
Nano-CT system characterized by a high-resolution, dual-target source, quasi-parallel beam. Enables phase contrast imaging. Very useful for light material samples like plants, polymeric composites, textile fibers, etc. Resolution down to 0.27 μm with a field of view of 0.9 × 0.7 mm.
High-quality data CT using a special helical trajectory, with a wide cone beam and an iterative reconstruction algorithm. A suitable system for cylindrical-shaped samples like drill cores or battery cells.

Techniques
Through the use of our advanced CT systems we offer reconstruction 3D models of sample morphology, volume quantification, identification of bulk density, particle distribution and orientation, porosity and permeability, and simulation of fluid, electrical, or thermal flow. Our infrastructure of CT equipment allows for a voxel resolution down to 270 nm (n-CT) and for samples up to dimensions of 500 x 800 mm (μ-CT).
Our LIBS technology offers multi-elemental detection (including Li, Be, and H), elemental imaging, large scale analysis up to 100 x 100 mm2, and hyperspectral data processing, which includes unsupervised clustering and image segmentation, registration of multimodal data, automated mineralogy, and quantitative analysis.
