A new infrared light source with unprecedented sensitivity allows molecular fingerprints of cancer cells.
Ultrafast infrared spectroscopy has shown that long-lived sub-structures exist in liquid water by measuring the vibrations of the O–H bonds.
Fourier transform infrared spectroscopy and imaging of dragonfly, damselfly and cicada wing membranes
Mark Tobin and colleagues describe “Fourier transform infrared spectroscopy and imaging of dragonfly, damselfly and cicada wing membranes”. Insects and plants have evolved highly specialised surfaces such as being highly water repellent or superhydrophobic, which also confers self cleaning properties. This is of interest to materials scientists to help in the development of manufactured materials with similar properties. High spatial resolution FT-IR spectroscopy and imaging provide useful information about the complex chemical patterning that contributes to this functionality.
A microscope being developed at the US Department of Energy’s Oak Ridge National Laboratory will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and beneath the surface.
Diseases like Alzheimer’s are caused when proteins aggregate and clump together. Using atomic force microscopy and infrared spectroscopy, EPFL scientists have successfully distinguished between the disease-causing aggregation forms of proteins. The finding can help change pharmaceutical treatment of neurodegenerative diseases.
The Center for Structural Biology and Bioinformatics at the Free University of Brussels (Université Libre de Bruxelles, ULB) has developed expertise in the analysis of biological molecules using infrared spectroscopy. Now, with the help of Scottish microarray instrumentation company, Arrayjet, the Center has integrated microarray technology to speed up and enhance the analysis of bio molecules such as proteins, which are exposed to hundreds of experimental conditions on a single chip using infrared imaging.
Berkeley Lab researchers’ novel diffraction spectroscopy technique will provide insight to chemical processes at important battery interface.
A new technique combines electron microscopy and synchrotron x-rays at Brookhaven Lab to track chemical reactions under real operating conditions.
Karsten Hinrichs and Andreas Furchner describe “Infrared mapping spectroscopic ellipsometry”. Recent developments in fundamental and materials research have increased the value of mapping techniques such as ellipsometry. IR ellipsometry, since it operates in the mid-IR fingerprint region, provides complementary information on composition, structural properties and interactions
Monitoring of catalytic reactions and catalyst preparation processes in liquid phase systems by combined in situ spectroscopic methods
In situ spectroscopic methods such as infrared, Raman and UV/vis spectroscopy are powerful tools to gain insight into reaction mechanisms and catalyst actions in homogeneously catalysed reactions. These methods and combinations of them offer great potential for the real-time monitoring of reactions in the liquid phase, for mechanistic studies as well as process control and kinetics.
Custom/OEM FT-IR engine based on the IRD 3 (an established, dedicated vapour-phase GC-IR detector). Versions are available with spectral ranges of 8000–400 cm–1 (with standard KBr beamsplitter), 6000–600 cm–1 (with optional ZnSe beamsplitter) and 12,000–1800 cm–1 (optional CaF2 beamsplitter). Resolution is 2 cm–1. Can be supplied sealed and desiccated or nitrogen purged.
ATR Pro One
Single-reflection ATR accessory using a newly designed monolithic diamond crystal to provide much higher throughput. A “torque limiter” pressure applicator ensures reproducible sample pressures. A high-throughput model is optimised for mid-IR measurements and a broadband model for use into the far-IR. ZnSE or Ge crystal kits are available.
Spotlight FT-IR Microscope Systems
Offering automated setup and complete characterisation in a short time for a wide range of applications. Available with either the Spectrum Two or Frontier FT-IR spectrometers.
Super-Sealed Liquid Flow Cell
For continuous flow IR transmission applications with a large port diameter permitting high flow rates. Designed for optimised laminar flow. Available with customer’s selection of sampling pathlength and window materials.
FT-IR ISO/IEC 17025 Wavelength Reference
Polystyrene film reference certified under ISO/IEC 17025 and traceable to NIST SRM 1921b for those in regulated industries and who need to comply with USP Chapters 854 and 1854. The references are card-mounted films and are supplied with a Certificate of Calibration listing wavenumber values for 14 peaks from 539 cm–1 to 3082 cm–1. They are available in two thicknesses: 38 µm for mid-IR and 65 µm with some additional peaks in the NIR.
Hand-held spectrometer that combines both FT-IR and Raman spectroscopies in a single instrument. Libraries are included to enable operators to identify unknowns ranging from explosives and chemical warfare agents to industrial chemicals and precursors. Switching between the two techniques is quick and is done via either the keypad or touchscreen. A motorised anvil adjusts sample pressure based on user settings for FT-IR analysis. Built-in safety features including a scan delay also increase protection from potentially hazardous substances.link.spectroscopyeurope.com/27-02-061
Thin Film Production of Plastic/Polymer Materials Using the Mini-Film Maker Accessory P/N GS03970 – Application Note 43
IR spectroscopy is a useful tool for group chemical species identification of a wide variety of sample materials, particularly for the classification of “organic” chemical materials based upon carbon atoms being present in the molecular structure. Many plastic and polymeric type samples which can be included in the category of organic molecular materials can be classified into particular “family” groupings and it is possible to identify the sample family types both qualitatively and quantitatively by use of the Attenuated Total Reflectance (ATR) technique as an IR measurement. (See - Specac Application Note 42).

Shedding light on plant biology by Fourier transform infrared spectroscopy of pollen” by Boris Zimmermann and Achim Kohler. Currently, pollen identification is mostly done under a light microscope. FT-IR spectroscopy of pollen grains provides rapid and simple identification of pollen, with the added benefit of providing environmental information.
