Aloe Vera Raw Material Screening
Aloe vera extracts are commonly used in cosmetics, nutritional supplements and medicines, and are thought to have healing and soothing properties. They are a common ingredient of lotions, yoghurt, drinks and desserts, and also facial tissues for consumers with sensitive skin. Given the demand for this versatile plant, it is vital that the identity, quality and quantity of key components are checked thoroughly, in both the raw extract and the finished product. ...

Wine Safety and Quality Control using High-Resolution FT-NMR
Frequent wine scandals in recent years have demonstrated a need for a technology that can rapidly assess both quality and safety, yet be simple to use and deliver on a number of important parameters. A new solution performs wine analysis using proton NMR spectroscopy at 400 MHz, which includes straightforward sample preparation, rapid measurement and fully automated analysis, resulting in the simultaneous measurement of a set of key quality and safety relevant parameters. ...

Why Do Thin-Film Silicon Solar Cells ‘Age’?
A unique project is examining why non-crystalline silicon suffers certain ‘aging effects’ and why the current efficiency of thin, amorphous silicon layers decreases steadily within the first thousand operating hours. The joint solar energy research project is seeing EPR solar scientists across five institutes collaborating research driven by ultra-high-resolution EPR spectroscopy. The project began in 2008 with funding from the German Federal Ministry of Education and Research (BMBF) and now, with a further ... Continue reading

Podcast Download - Assisted, Automated High Throughput NMR Workflow
In this podcast Till Kuehn, Product Manager for Small Molecule NMR at Bruker talks about the trend in NMR towards smaller volumes, higher throughput and the need for more automation. NMR is now being used in new areas such as Quality Control, and labs now routinely run 20, 30 or even 50,000 samples. The solution to analysing more and more samples lies with 'assisted analysis', using analysis algorithms to automatically process data ... Continue reading

Food Irradiation Control Using EPR
Worldwide, it is estimated that more than 500,000 tons of food and dietary supplements are treated with radiation with spices and vegetable seasonings making up the majority. Though this amount is small compared to the amount of food produced both the current standards for consumer protection and the need for a traceable and transparent food production chain demand a proper food control strategy. National authorities are responsible for issuing a clearance list ... Continue reading

Rapid, automated analysis for optimizing your beer’s shelf life
Oxidative staling of beer occurs by a free radical process. During storage, even trace amounts of transition metals such as iron or copper will catalyze the conversion of molecular oxygen to what are known as “reactive oxygen species” (ROS). One such ROS is the hydroxyl free radical which rapidly oxidizes components of the beer to free radicals. Beer-derived free radicals react further to perpetuate a chain reaction that results in carbonyl end products such as aldehydes and ketones. It ... Continue reading
