From Pharmaceutical to Agricultural Applications: What’s New in NIR?

April 01, 2016

Spectroscopy

Near-infrared (NIR) spectroscopy offers quick analysis with no sample preparation for many fields, but it is particularly popular for process monitoring, materials science, and medical uses. NIR has also seen applications in agriculture from the very start of the technique, but new instrument capabilities are poised to offer even more to that field. Benoît Igne, a principal scientist at GlaxoSmithKline in King of Prussia, Pennsylvania, recently spoke to us about his work using NIR and areas where he thinks the technique has growth potential, specifically process analytical technology and agriculture.

Analysis of the State of the Art: Near-Infrared Spectroscopy

June 01, 2015

Spectroscopy

In honor of Spectroscopy's celebration of 30 years covering the latest developments in materials analysis, we asked a panel of experts to assess the current state of the art of near-infrared (NIR) spectroscopy and try to predict how the technology will develop in the future.

An interview with Charles Wilkins, the winner of the 2013 American Chemical Society Division of Analytical Chemistry Award in Chemical Instrumentation, sponsored by the Dow Chemical Company.

Scattering Impact Analysis and Correction for Leaf Biochemical Parameter Estimation Using Vis–NIR Spectroscopy

July 01, 2011

Spectroscopy

Simulated leaf spectral data were generated to analyze scattering impact and then compared to experimental data to validate the conclusions of the simulation.

Miniature Optical Spectrometers: The Art of the Possible, Part IV: New Near-Infrared Technologies and Spectrometers

September 08, 2009

Spectroscopy

Part II of this series described many of the miniature optical technologies that were developed as a result of the telecommunications boom, and Part III covered conventional small near-infrared (NIR) spectrometers. Here, in Part IV, we bring those themes together and see how the massive investment in telecommunications, microelectro- mechanical systems (MEMS), and micro-opto-electro-mechanical (MOEMS) is starting to impact NIR spectroscopy.

NIR Spectroscopy -- A Noninvasive Mind-Reader?

April 21, 2009

Canadian researchers at the Bloorview Research Institute (Toronto, ON, Canada) and the University of Toronto have developed a way to use optical imaging to decode preference by measuring the intensity of near-infrared light absorbed in brain tissue.

Hubble Finds Hidden Exoplanet

April 03, 2009

Using a powerful new image-processing technique, researchers at the University of Toronto (Ontario, Canada) have identified an exoplanet in images taken in 1998 with the Hubble Space Telescope's Near-Infrared Camera and Multi-Object Spectrometer (NICMOS).

Mind-Controlled Robots Using NIR Spectroscopy
