Galaxy Scientific’s App Note: Detecting Counterfeit Drugs Using FT-NIR
AZo Materials has published the latest application note from Galaxy Scientific
A suitable technology is needed to quickly, easily, and inexpensively screen medical drugs to detect fake products and poor quality ingredients. Traditional wet chemical or chromatographic methods cannot be used as fast screening tools as they are time consuming and require expertise in sample preparation and handling. However, near infrared (NIR) spectroscopy is rapid, non-destructive, and can be used to differentiate and quantify organic compounds. With no complex sample preparation, NIR spectroscopy can be extremely inexpensive per sample. NIR spectroscopy can also differentiate between generic formulations that are sold as brand name drugs. The most impressive example of using NIR spectroscopy as a counterfeit drug screening tool comes from the People’s Republic of China. Researchers at China’s National Institutes for Food and Drug Control (NIFDC) have equipped 200 vans with FT-NIR spectrometers turning them into mobile labs for counterfeit drug testing.
