Curtis Marcott, Tadashi Awatani, Jiping Ye, David Gerrard, Michael Lo and Kevin Kjoller give us a “Review of nanoscale infrared spectroscopy applications to energy related materials”. Fuel cells, photovoltaics and specialised polymers for fracking are all considered.

This article describes an application of spectral imaging for the differentiation of tumour and normal cells. The authors also introduce the concept of a spectral barcode, which has had success with some tissues and has potential in others.

With continuing food scares around the world, food producers need every tool they can get to prevent contamination of their products at every stage of production. Hyperspectral reflectance imaging in the NIR combined with chemometrics shows much promise for the detection and identification of foreign bodies among food grains.

There are a number of approaches, and by combining FT-IR imaging methodology with microfluidics devices, the opportunity to study live cells by FT-IR imaging in controlled environments is now possible.

The TEL-1000 MW InSb high-performance infrared camera has been launched by Telops. The camera covers the 3.6 µm to 4.9 µm wavelength range and can be customised to cover an extended range from 1.5 µm to 5 µm. It can capture up to 200 frames per second at full frame (640 pixels × 512 pixels) and up to 600 frames per second when windowing (320 pixels × 512 pixels). It features patent-pending real-time processing and real-time temperature calibration. It can also be equipped with automatic exposure control in order to adjust the exposure time according to the scene’s dynamic temperature varions.

The SpectroCam multispectral imaging camera from Ocean Thin Films is now available with new analysis software. The software has a simple, intuitive graphical interface that allows users to quickly perform several image processing and analysis functions. Results can be viewed as live image output or saved to a variety of image file formats. The software processing is a useful tool for extracting MSI information and can even create colourised NIR images. In addition, the analysis portion of the software provides live, quantitative information regarding image intensity as a function of spectral wavelength for a user-defined image or image cross section. Applications include water quality measurement, product screening, machine vision, medical imaging, surveillance and authentication.

Telops has introduced the new improved Hyper-Cam Weatherproof which provides high-performance hyperspectral imaging capabilities but with an upgraded weather­proof enclosure. It has an extended temperature range which covers –20°C to 40°C and can be stored at temperatures between –40°C and 70°C. The system is IP rated, with a high resistance to rain and dust, enabling users to benefit from high quality spectral imaging without worrying about changing environmental conditions during field measurements. The upgrade enables the system to be easily used in a number of applications including stand-off chemical detection and identification, military target signature analysis, flare measurement and leak detection.

Due to the importance of imaging mass spectrometry in the life sciences, the Joint Committee of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has decided, as part of the “Imaging Mass Spectrometry in the Life Sciences” initiative, to equip nine universities with major instrumentation systems.

After an introduction to MALDI, DESI and SIMS, the authors describe their main applications in forensics, as well as the advantages provided in terms of sample preparation over approaches routinely used in toxicological laboratories.

Ninety-five delegates attended the 8th Confocal Raman Imaging Symposium in Ulm, Germany, from 5 to 6 October organised by WITec. Featuring a global line-up of Raman Imaging experts, the symposium gave scientist the opportunity to see the newest applications and relevant instrument configurations.

Thermo Fisher Scientific has introduced a new imaging ATR accessory offering enhanced spatial resolution and high-speed data acquisition capabilities for FT-IR chemical imaging applications. This accessory has been designed to seamlessly and effortlessly integrate with the company's range of FT-IR microscopes to enable improved chemical imaging of challenging samples. It is of particular benefit to manufacturers of composite structures, paper products, pharmaceutical dosage forms, biological tissues, polymer films and coatings. It simplifies the task of obtaining high-quality IR spectra in cases of samples that are difficult to prepare for transmission analysis. Observable features in specimens, such as defects, particles, fibres or inks, may be analysed with improved spatial resolution. It can quickly snap into the sample hold feature of the Nicolet iN10, Nicolet iN10 MX and the Nicolet Continuµm microscopes without the need for tools. All standard optics remain available, avoiding any concerns of alignment or down time when switching between sampling modes.

Princeton has introduced the PyLoN series, a new line of controller-less, cryogenically-cooled CCD cameras, designed for quantitative spectroscopy applications that demand high sensitivity. The first commercially available models in this series are the 100 and 400 dual-amplifier modules that utilise 1340 × 100 and 1340 × 400 sensors, respectively. In creating the new platform, the company redesigned their Spec-10 family of cameras to remove the external controller, increasing experimental flexibility while improving the ultra-low-noise electronics. Liquid nitrogen cooling in the new cameras virtually eliminates dark current, indium metal seals enhance vacuum longevity and binning noise has been reduced from the levels of the Spec-10 platform. Other features include ADC conversion up to 4 MHz, kinetics mode which allows microsecond-resolved kinetic spectral acquisition and custom sensor mode for increased control over the camera readout. The cameras operate on 32-bit and 64-bit Microsoft Windows operating systems and are fully supported by LightField 64-bit data acquisition software featuring IntelliCal wavelength and intensity calibration packages. The GigE interface allows remote operation via a single cable without the need for custom frame grabbers. The cameras area available with or without a 40 mm shutter.
