Supreme Performance and Accuracy for Infrared Analysis
Shimadzu’s middle class Fourier Transform Infrared Spectrophotometer, IRTracer-100, analyses materials quickly and easily in a variety of fields such as pharmaceuticals, food, chemicals and electronics, and monitors high speed reactions within a few seconds.
Compared to the well-reputed predecessor model, IRPrestige-21, the easy-to-operate IRTracer-100 features highly improved sensitivity, resolution and scan speed with expandability and easy maintenance. IRTracer-100 can quickly and easily obtain high quality data of small samples through 1.5-times higher
sensitivity and high speed scanning of 20 spectra/sec.
IRTracer-100 achieves 60,000:1 SNR (signal-to-noise ratio) with improved interferometer and detector, and high speed reaction monitoring function for these demands. Combining with the LabSolutions IR Contaminant analysis program makes analysis of small samples easier, quicker and more accurate. LabSolutions IR on IRTracer-100 can be connected to Network system with LabSolutions software for LC/GC, and unifies management of obtained data and users to access the systems for pharmaceuticals demands.
IRTracer-100 can quickly and easily obtain high quality data of small samples from 1mm to 10µm. LabSolutions IR analysis program achieves results within a few seconds – compared to one hour duration using conventional means. IRTracer-100 also obtains high quality spectra of ppm-order additives and identifies them easily. Shimadzu’s predecessor model IRPrestige-21 recorded spectra every 5 seconds, but the IRTracer-100 can obtain 20 spectra in a second in rapid scan mode (option). IRTracer-100 precisely monitors high-speed reactions such as curing of UV curable resin.
LabSolutions IR on IRTracer-100 enables connection to other laboratory hardware, for example LC and GC systems, and unifies management of obtained data. The number of spectra in standard IR libraries has been expanded from 1,000 to 12,000, and identification of unknown samples can be done with the standard system. The unique Easy Macro program supports easy-to-use operation, even by less-experienced operators.

New Variable-Energy Electron Ionisation Technology Launched
Markes International has announced the launch of a variable-energy electron ionisation source technology for GC–MS, Select-eV®
. By enabling the energy of ionising electrons to be changed, Select-eV breaks new ground in the field of
GC–MS. It allows the production of reference-quality electron ionisation mass spectra with conventional full- fragmentation patterns, and repeatable ‘soft-ionisation’ spectra exhibiting reduced fragmentation and an enhanced molecular ion.
Previous attempts to develop soft electron ionisation have been compromised by a dramatic drop in sensitivity. Other approaches to soft ionisation have also been limited by the inconvenience of reagent gases or source exchange. Select-eV overcomes all these problems by maintaining or enhancing sensitivity, without the need to reconfigure the system or add reagents.
Nick Bukowski, Mass Spectrometry Business Unit Manager at Markes, said “Using Select-eV, the desired ionisation energy is simply selected as part of the method setup in the controlling software. Energies can be varied anywhere from standard 70 eV down to 10 eV. The molecular ion is enhanced at lower energies but a degree of structurally significant fragmentation is also maintained. This makes Select-eV perfect for any GC–MS analyst needing further confirmation of compound identity, or wanting to distinguish between compounds with spectra that are very similar at 70 eV.”
Bukowski added “Lowering the energy of electron ionisation usually causes a dramatic drop in sensitivity, but Select-eV overcomes this problem. In fact, the signal-to-noise ratios of many compounds are increased at lower energies. This is a crucial advantage of Select-eV for trace analysis and for challenging samples such as the complex mixtures of hydrocarbons routinely investigated in the petrochemical industry.”
Select-eV is available with the BenchTOF range of time-of-flight mass spectrometers from Markes International, which enjoy increasing popularity in the GC–MS field for their high degree of sensitivity and the production of ‘reference-quality’ spectra, alongside numerous productivity advantages for the analyst.
Markes is launching Select-eV and the newly updated BenchTOF line of mass spectrometers at the HTC-13 conference in Bruges, Belgium, from January 28. The company will also be presenting their world-leading range of innovative thermal desorption technology for automated extraction/ concentration of trace organics in air and materials.

NMR System used for Fuel Analysis Research at the Instituto de Quimica
Magritek report on the use of their Spinsolve Benchtop NMR spectrometer for research at the Instituto de Quimica, University at Campinas in Brazil.
The Institute of Chemistry is dedicated to training students in chemistry and chemical technology as well as teachers of Chemistry. Professors Jose Jarbas and Pasquini Celio lead a group of research scientists in the use of NMR spectrometry. Their student, Mario Killner takes up the story.
Mario Killner spent a year in the renowned NMR laboratory of Professor Bernhard Bluemich at the Technical University of Aachen in Germany. He was working on the development of test methods to monitor biodiesel production. This was based on diesel fuel quality parameters developed in German industry. The success of this work led to the purchase of the Magritek Spinsolve Benchtop NMR spectrometer.
Describing his work, Mario talks first about previous experimental methods. “This is the first time that our group has had access to NMR in our laboratories. For a long time, our research group has been working mostly with NIR spectroscopy and, most recently, with Terahertz spectroscopy to develop new methodologies applying chemometric tools.”
Continuing, he said, “Now we’d like to implement the NMR spectroscopy in our research starting with analysis of fuel. We want to create new methodologies applying NMR with chemometric tools for quality control of Brazilian fuels which will mainly be gasoline and diesel. We believe that the benefits of using NMR will be on the speed of analysis, the cost of analysis and also the possibility of automation sometime in the future.”
Magritek’s latest Spinsolve system allows 13C NMR Spectroscopy. It delivers more detail in its spectra than use of the more basic 1H nucleus. Carbon has a large chemical shift range of approximately 250 ppm and using composite pulse decoupling there is usually a single peak per carbon atom in the molecule making carbon spectra much more informative than proton spectra.
Furthermore, multinuclear and multidimensional experiments reveal additional structural information such as how carbon and proton atoms in the molecule are connected. This enables NMR to easily resolve isomers that are often confused with other analytical methods.

Raster Orbital Scanning Technology Recognised at TASIA Awards
The Raster Orbital Scanning (ROS) feature of the IDRaman family of products from Ocean Optics has been recognised as one of 2013’s 15 best innovation technologies by The Analytical Scientist magazine, an industry publication. ROS is a novel Raman spectroscopy sampling technique that helps to derive more accurate and comprehensive measurement results. The IDRaman mini handheld Raman spectrometer and the IDRaman reader integrated Raman spectrometer both feature ROS.
ROS increases the sensitivity of Raman measurements up to 10 fold by rastering a tightly focused laser beam over a larger area, encountering more Raman- active compounds. The reduction of the background by ROS provides a more accurate result and is especially ideal for applications like surface enhanced Raman spectroscopy (SERS). Rastering a tightly focused beam allows the resolution of measurement to be mainlined, ensuring accuracy for applications that rely on library matching.
ROS offers the advantage of allowing higher laser powers to be used for measurement without damage to the sample. This supports the development of low-cost Raman detection in mainstream applications such as anti-counterfeit and medical diagnostics. By scanning a larger area with a the laser beam, The Analytical Scientist points out that conventional paper could be used as a SERS substrate for a point-of-care diagnostic tests, as opposed to pristine surfaces.
“This unique sampling technique helps make Raman measurements more accurate and reliable, enabling our customers to do more,” said Richard Pollard, President of Ocean Optics. “We are excited to hear that Raster Orbital Scanning has received this award.
