Our laboratory combines advanced imaging and analytical instruments to investigate the physical properties, internal structures, and composition of agricultural and food materials. Our facilities include hyperspectral imaging, X-ray imaging and micro-computed tomography, single-kernel characterization, and nitrogen and protein analysis. Together, these capabilities support research in seed and grain quality, food characterization, and the development of non-destructive assessment methods. A selection of our laboratory instruments and their capabilities is presented below.

X-ray Micro-CT Scanner
X-ray Micro-CT Scanner
The SKYSCAN 1275 (Bruker) provides non-destructive, three-dimensional imaging of internal sample structures using X-ray micro-computed tomography. It enables visualization and quantitative analysis of internal features, supporting research into seed and grain morphology, structural defects, and porosity.
Short-Wave Infrared Hyperspectral Imaging System
Short-Wave Infrared Hyperspectral Imaging System
Our SPECIM SWIR line-scanning system acquires images across 1000–2500 nm, with 288 spectral bands. This spectral range supports investigations of composition-related differences in agricultural and food samples, including the development of calibrated models for predicting moisture and other quality attributes.
Visible–Near-Infrared Hyperspectral Imaging System
Visible–Near-Infrared Hyperspectral Imaging System
Our SPECIM Vis–NIR line-scanning system captures spatial and spectral information across 450–1000 nm, with 224 spectral bands. The system supports research into sample variability and the development of imaging methods for assessing seed, grain, and food quality.
Cabinet X-ray Imaging System
Cabinet X-ray Imaging System
The Faxitron system produces two-dimensional X-ray images that reveal internal sample features without physical sectioning. It supports the inspection of seeds and grains for internal damage, structural abnormalities, and differences in kernel filling.
Single Kernel Analyzer
Single Kernel Analyzer
The Petren single kernel analyzer characterizes individual wheat kernels by measuring hardness, weight, size, and moisture content. These measurements reveal variation within grain samples and support studies of grain quality and milling characteristics.
Nitrogen and Protein Analyzer
Nitrogen and Protein Analyzer
The LECO FP628 determines nitrogen content in organic samples using combustion analysis. Protein content is calculated from the measured nitrogen using an appropriate conversion factor, supporting compositional analysis of grain, flour, and other agricultural and food materials.
