Using fNIRS to track the brain activity of both participants, when people are asked to cooperate with a partner, found that males and females had different patterns of shared brain activity.
Unity Scientific has introduced the SpectraStar XT series of NIR spectrometers.
Infrared spectroscopic techniques for the non-invasive and rapid quality control of Chinese traditional medicine Si-Wu-Tang
Christian Huck and co-authors look at “Infrared spectroscopic techniques for the non-invasive and rapid quality control of Chinese traditional medicine Si-Wu-Tang”. They have used benchtop mid-IR and NIR as well as portable NIR instruments for quick and non-invasive quality control of this traditional Chinese medicine. Adulterations could be detected, as well as the raw herbs and different sources of the Si-Wu-Tang. The success of the mobile NIR instrument is particularly interesting due to the growing interest in such technology for its ease-of-use and cost.
Researchers at University of Texas Southwestern Medical Center, Dallas, USA, have determined that light reflectance spectroscopy can differentiate between malignant and benign prostate tissue with 85% accuracy.
Electro-optic modulators, which can switch light on and off within just picoseconds, are enabling ever faster telecommunication over fibre optics, and the same tools have now been harnessed for high-speed and accurate molecular sensing in the near infrared.
ChromaDex and American Laboratories have announced the release of a Fourier transform near infrared (FT-NIR) spectroscopy based identification method for the positive identification of desiccated bovine and porcine glandular tissues used in nutritional product formulations.
This product focus is on Molecular Spectroscopy.
The 2015 Eastern Analytical Symposium Award for Outstanding Achievements in Near Infrared Spectroscopy has been presented to Benoît Igne.
Kappa number analyser FITNIR Analyzers has launched the latest addition to its suite of process analysers. The FITNIR Kappa measures the kappa number of wood pulp, which plays a critical role in the efficiency of digester and bleaching operations. Wet pulp samples are simply washed with water and pressed into a pad, which is then analysed by the spectrometer within 20 s. Procurement applications and final product testing is also now possible. “FITNIR Kappa is the first of its kind to directly measure kappa number on dry pulp sheets without the use of chemicals, yet can provide rapid, reliable and accurate results,” explains Thanh Trung, VP of Technology. “The data from FITNIR Kappa lends itself to process optimisation, ensuring the target product quality is reached and maintained.” These uses are only the tip of the iceberg for this versatile technology. Applications are already available for Air Dry (AD) content, while many other possible parameters for improving product quality are in development. FITNIR Kappa represents a paradigm shift in how pulp properties measurement is done. Its simplicity reduces operator-to-operator variability, while providing faster, more accurate results for improved efficiency and profitability. http://www.fitnir.com/kappa

SeaWave NIR spectrometer The Seawave from Radiantis is a near infrared spectrometer with no moving parts, small footprint, a data acquisition speed of >1000 spectra/second and resolution of 3 nm for a broad detection range in the IR (900–1700 nm). It is based on Hamamatsu InGaAs linear array sensors, and its small size and light weight make it suitable for integration into in-line and off-line analysers for the food and pharmaceutical industry, as well as handheld analysers for routine process testing. It features a versatile entrance aperture which incorporates both a standard fibre input connector to bring light into the device through an optical fibre and a slit which enables free space input coupling. A USB 2.0 interface connects it to a PC, and DLLs and customised control software packages for specific requirements are provided. The higher resolution (<3 nm) is achieved at the expense of shorter detection ranges; extended spectral ranges (>1700 nm) are also available upon request. http://www.radiantis.com/instrumentation/seawave-ir-spectrometer

Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms
In the Tony Davies Column, we learn about “Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms”. With the increase in trafficking of counterfeit medicines and other products, there is a need for definitive results from an on-site analyser useable by customs officers. The German authorities have commissioned the development of a multi-modal, transportable inspection system, including intelligent data processing and evaluation, for fast spectroscopic recognition of illicit drugs and counterfeit medicines. This is described in the column.
In initial tests, a novel near infrared spectroscopy device assesses shock severity as accurately as a standard blood sample, without a single needle prick.
Fully integrated NIR spectrometer and light source the size of a computer mouse. Covers the range 1300–2200 nm (although customisation of this is available) with a spectral resolution of 10 nm. It is powered via a USB port, although an embedded battery is available as is W-Fi or Bluetooth data transfer. Software is provided for qualitative and quantitative analysis.
