Chart of Common NIR Absorption Bands

Free Printed Poster or PDF for your Lab, Office, or Conference Room

Galaxy Scientific, a manufacturer of FT-NIR instrumentation for industrial use, is pleased to offer a Chart of Near-Infrared Absorption Bands in printed poster or PDF format.

This chart shows the wavenumber and wavelength ranges corresponding to common NIR absorbance peaks used in optical spectroscopy.  The chart covers the optical range of 4000 cm-1 to 14000 cm-1 (or 2500 nm to 700 nm) and shows the combination bands as well as first, second, and third overtones for common functional groups. The functional groups covered include the following: CH, CH2, CH3, CHO, NH2, OH, ArOh, ArCH, CONH2, and H2O.  Use these common functional groups to look up where to expect near-infrared absorptions in edible oils, polymers, sugars, and other organic materials.

You can download a free PDF of this chart here.

If you would like a printed version of this poster to hang on your lab, office, or conference room wall, please simply fill out the form below and click send.  Sorry, but we can only offer this to people in the USA and Canada.

Detecting Counterfeit Drugs with FT-NIR

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.
