This Product Focus is on Hand-Held and Mobile Spectroscopy; a number of companies have provided information on their key products, their applications and features.
A person-portable capillary gas chromatoraph-toroidal ion trap mass spectrometer with high-speed temperature programming and a miniature toroidal ion trap mass spectrometer with a nominal mass resolution over a mass range of 50 Da to 500 Da. It is totally self-contained, weighs less than 32 pounds with all accessories, is battery operated and has on-board helium GC carrier gas supply cartridge.
A handheld Raman system for rapid identification of suspected narcotics, without direct contact for most samples. A single test for multiple controlled substances provides narcotics officers with clear, definitive results for presumptive identification with no user interpretation. Lightweight and easy to use. Captures all scan results and self check results to help expedite prosecution, and the Admin software stores all scan results with time and date stamps.
Micro and macro portable real time Raman imaging system. Uses a wavelength sweep which can acquire the full Raman spectrum of all the positions of an image at once. Can acquire and display both the Raman and visible images simultaneously.
A compact personal UV/vis microvolume spectrophotometer. It is small enough to fit into a drawer but powerful enough to help accelerate life science workflows related to sequencing, PCR/qPCR, protein isolation, antibody production and HLA typing.
Portable spectrometer based on CCD detection with features including spectrum scanning, photometric, quantitative and kinetic methods. Embedded software and touch screen interface allow for ease of use and data storage, which can be transferred to a PC via a USB connection. Viewer software provides data interpretation and reporting functionality. The C30M comes with pre-programmed test methods for the Spectroquant.
The latest version of Spectrotest from Spectro Analytical is a mobile OES spectrometer, which is capable of segregating Duplex steels by nitrogen content and measuring carbon in steels down to 0.1% without the need for argon flushing. A number of advances in technology have made this possible. The “Plasma Generator” totally digital spark control accurately defines and controls the energy in the plasma which improves performance. The sample probe is new too: it is lighter, slimmer and more convenient to use when space is restricted. A new scrubbing system improves optical performance to permit the measurement of carbon in low alloy steels in air. An optional probe, which can quickly be interchanged with the standard probes, permits the measurement of light elements such as N, P, S, Be and B. The system uses Spectro's ICAL, which monitors performance and automatically corrects for any calibration drift using a single control sample. For PMI, alloy grades are quickly identified against the instrument's internal libraries and the automatic programme finding function uses the measured spectrum to ensure that the best measurement parameters and programmes are used for the sample.
Agilent Technologies Inc. is to buy specific assets of A2 Technologies. These include substantially all of A2 Technologies' intellectual property, technology, employees and its spectroscopy product portfolio. Subject to customary closing conditions, the transaction is expected to be final in mid-February. Financial details were not disclosed.
A laser-induced breakdown spectroscopy (LIBS) instrument will be one of the ten science instruments on NASA’s next Mars rover, known as Curiosity. The Chemistry and Camera (ChemCam) instrument on the rover uses a laser to excite a spot on rocks and produce an ionised gas which is observed through a telescope and analysed to identify the chemical elements in the target.
Biomedical engineers are developing a hand-held device called a SpectroPen that could help surgeons see the edges of tumours in human patients in real time during surgery. Statistics indicate that complete removal, or resection, is the single most important predictor of patient survival for most solid tumours.
A2 Technologies has announced the availability of two new diffuse reflectance mid-infrared spectral libraries of rocks and minerals, further extending the use of their Exoscan and FlexScan hand-held FT-IR analysers. The first library contains spectra of general rocks and mineral sources around the world, while the other is focused on commercially important or strategic minerals.
A new accessory from Ocean Optics is broadening the range of applications for its field-portable spectrometers. The StediQ provides a temperature-controlled atmosphere, helping to stabilise temperature effects and eliminate temperature drift in inclement conditions or extreme temperatures from –20°C to 50°C. Available in both UV (200–1100 nm) and vis-NIR (400–25 nm) versions, it interfaces with the company's USB2000+, USB4000, HR2000+, HR4000, Maya2000, Maya2000Pro, QE65000 and NIRQuest spectrometers. In extreme hot or cold conditions, the unit operates independently from outside temperatures. It connects easily to the spectrometer with preconfigured plug-ins and communicates via the spectrometer's USB port.

CSIRO scientists have developed a new technique using a hand-held FT-IR spectrometer for the rapid on-site detection and quantification of petroleum hydrocarbons (commonly derived from crude oil) in soil, silt, sediment or rock.
Selected ion flow tube mass spectrometry, SIFT-MS; new horizons in real time air and breath analysis
We conceive selected ion flow tube mass spectrometry, SIFT-MS, primarily as a real-time, absolute, analytical technique that can meet the challenge of the immediate analysis of humid exhaled breath for rapid clinical diagnosis and therapeutic monitoring. This objective has certainly been achieved and the application of SIFT-MS has quickly been expanded into many other areas where real time, immediate analyses of trace compounds in air are desired, as we have demonstrated in recent reviews and which we summarise at the end of this article.
The problem of detecting, recognising and identifying explosives at significant standoff distances has proved one of the most difficult—and most important—challenges during recent years, being today, one of the most demanding applications of spectroscopic techniques. The limited number of sophisticated available techniques potentially capable of standoff detection of minimal amounts of explosives is based on laser spectroscopy. Of the recently developed techniques, Raman spectroscopy and laser-induced breakdown spectroscopy (LIBS) are considered significant for their potential for homeland defence applications.
