Owners and managers of scrap-recycling companies know very well: profit is born not at the shear or the weighbridge, but at the sorting stage. Mix up stainless grades, let a nickel alloy slip into “heavy melt,” or miss lead in aluminum – and all your margin goes negative together with a claim from the steel mill. At the same time, visual inspection, a magnet, spark testing and ...
In the production of galvanized rolled steel products, it is critically important to strictly control the composition of metallic coatings. Modern protective coatings on steel – from traditional zinc to complex zinc-aluminum-magnesium alloys – contain alloying elements (additions) such as aluminum (Al), magnesium (Mg) and silicon (Si). These additions have a strong influence on the ...
Ilmenite and Its Significance: Where It’s Used and Why Composition Matters Ilmenite is a mineral—the primary source of titanium—occurring as iron–titanium oxide (FeTiO3). It is a raw material for producing titanium dioxide (TiO2), a widely used white pigment, and for metallic titanium. About 95% of all mined titanium feedstock is processed into TiO2 pigment used in paints ...
Introduction Effective quality control of solder joints is critical in the electronics industry. Precise monitoring of lead (Pb) and tin (Sn) content is essential, as incorrect Sn/Pb ratios can lead to soldering defects, reduced equipment reliability, and non-compliance with international safety regulations, such as the RoHS directive, which restricts hazardous ...
Introduction Soil is the foundation of agriculture and ecosystems, yet industrial activities and pesticides often introduce toxic metals like lead, cadmium, or mercury. Rapid assessment of soil composition is essential for farmers, environmental engineers, ecologists, and regulators. X-ray fluorescence (XRF) delivers multi-element results in minutes without complex lab work, making it an ...
Near-infrared (NIR) spectroscopy is a key technology in enabling rapid, non-destructive analysis of agricultural samples. By delivering real-time, actionable insights, NIR systems help optimize resource use, improve efficiency, and ensure consistent quality across the supply ...
When infrared light is absorbed by a sample, specific vibrations occur in the chemical bonds of the sample. ...
This technique utilizes the infrared absorption characteristics of specific functional groups in monosaccharide molecules to identify and quantify monosaccharides.Basic PrincipleIn ATR FT-IR analysis, infrared light passes through the sample, with some light being absorbed by the molecules in the sample and some being reflected. ...
Plastics can be divisive since they are convenient and inexpensive, yet have a harmful impact on the environment. These materials are found everywhere – from museums to modern medicine, and even in the ocean waves. Plastic is ubiquitous, and Raman spectroscopy can be used anywhere it is located for identification, classification, and quality testing ...

Background MeasurementMeasure the CD signal of the selected buffer without the protein to obtain the background spectrum.3. Sample MeasurementMeasure the CD signal of the protein sample in the range of about 190-250 nm.4. Data ProcessingSubtract the background spectrum from the CD signal of the protein sample. Convert the resulting differential ...
By measuring these absorption peaks, the chemical composition of the sample can be determined.Analysis Workflow1. Sample PreparationFor the preparation of solid samples for FTIR spectroscopy, KBr is used. ...
These sensors utilize advanced technologies, such as spectroscopy, to analyze soil samples and provide real-time data on nutrient levels. This data can then be used by farmers to accurately determine the amount of fertilizer required for optimal plant nutrition. ...

It measures the interaction of IR radiation with a sample, to provide chemical identification. The three main areas studied by IR are the near-IR 14000-4000 cm-1, mid-IR 4000-400 cm-1, and the far-IR 400-10 cm-1. ...
Raman spectroscopy was highlighted due to its powerful identification and discrimination abilities, whilst also offering a non-destructive technique keeping samples intact. In this blog post we highlight Raman spectroscopy’s skill at keeping your shopping basket safe, from methanol identification in drinking alcohol to identifying ...
When laser light is focused into a sample by a Raman microscope, a three-dimensional excitation volume is formed within the sample. ...
The technique is non-destructive, meaning the samples are unchanged after analysis and ready for further investigations back on Earth. ...
It can tell us a lot about our own body’s health.In a sample of blood, plasma makes up just over half of it, plasma is an aqueous solution made up mostly of water and proteins which serve many important functions in the body. ...
ODIN is proving to measure biological samples more effectively than has previously been seen and without degrading fragile samples (see Foster et al (2022)). ...
Personal care and cosmetic products are ubiquitous in our daily lives. Most of us wouldn’t readily go out to meet our peers without first practicing a bit of hygiene, which is why these products are so widely used. Personal care products and cosmetics are mainly applied externally (e.g., on hair, skin, and nails) as well as orally (e.g., on teeth, gums, and tongue) either for hygienic ...
