Physical purity testing of seeds
What is physical purity? Physical purity testing quantifies the weight percentages in a seed lot of
- pure seed
- other crop seeds
- weed seeds
- inert matter (other matter than seeds: broken seeds, chaffs, sterile florets, stems, and stones)
All species of seed and all types of inert matter present shall be identified. Physical purity testing is regulated by International Seed Testing Association (ISTA) rules.
Multispectral imaging for brand protection: Analysis of counterfeit packaging using the VideometerLab 3 multispectral imaging system
By Alex Bates (Analytik) & Dr Neville Broad (NWB Spectroscopy) Keywords: Videometer, Counterfeit, Packaging Materials Analysis
The rapid and reliable identification of counterfeit goods is the first step on the road to building a secure supply chain. Without a method of identifying those samples which are not genuine there is no way to narrow down the particular products that need additional security features, or which batch numbers consumers should be alerted to avoid via public health authorities. Counterfeiting poses a serious public health risk, and those who counterfeit should face the full force of the law; the reliability and accessibility of the VideometerLab results will help ensure a conviction when the counterfeiters are eventually discovered.
Streamlining QC in food, feed and pharmaceuticals using Rapid Multispectral Imaging
Rapid Multispectral Imaging (RMSI) is an emerging technique developed to ensure the quality and safety of food, feed and pharmaceutical materials. Parameters measureable by multispectral imaging such as colour, texture, gloss, shape and size give useful quality information on both raw materials and finished products. Multispectral imaging provides a rapid quality assessment of uniform and inhomogeneous samples alike by combining information on all of the above parameters automatically in just a few seconds, requiring no sample preparation and leaving the sample intact.
Spectral Imaging is an emerging technique which enables extensive characterization of a wide sample range. Early adopters of multispectral imaging in the agricultural industry have been able to replace subjective and expensive sensory panels with this technology.

Multispectral imaging unlocks valuable information on both quality and safety of pharmaceutical materials. Parameters measureable by multispectral imaging such as colour, texture, gloss, shape, and size provide useful information on a finished product, on the raw materials, or on the manufacturing process itself. Multispectral imaging provides a rapid quality assessment of uniform and inhomogeneous samples alike by combining information on all of the above parameters automatically in just a few seconds, requiring no sample preparation and leaving the material intact.
Seeing objects in a new light with multispectral imaging
Keywords: Imaging, Anti-counterfeiting, Dermatology, Cosmetics, Forensics, Heritage
Multispectral imaging provides valuable information on the quality and safety of a vast array of materials from pharmaceuticals to raw meat and burned biscuits. The same imaging techniques can be used to measure skin sensitivity to sticking plaster, detect counterfeit drugs and packaging and gain insight into historical artefacts such as mediaeval manuscripts and weapons. This article attempts to highlight some of the newest applications in multispectral imaging, these diverse applications converge as they all in some way have parameters measureable by the technique such as colour, texture, gloss, shape and size which when combined give previously unseen information.
