Agilent Technologies has announced that it is replacing the signal-to-noise specification with a new instrument detection limit specification for its 7000B triple quadrupole GC/MS system. The company considered IDL is a better measure of GC/MS/MS performance as it follows guidelines of IUPAC, US EPA and other organisations. IDL calculates typical performance from a series of automated injections for an accurate view of system performance. The Student's t-test is applied to eight consecutive injections of 100 fg OFN using a 99% confidence interval. In addition, the IDL specification confirms the performance of every component in the system from the autosampler through to the detector. The IDL specification of the 7000B system in EI mode is 12 fg OFN.
The new Spirit from Spectra Physics is a compact, industrial grade, ultrafast amplifier with software-adjustable repetition rates up to 1 MHz.

Featuring a rugged one-box design, the laser delivers ultrashort 400 fs pulse widths with high energy of 20 µJ per pulse.
The Winescreener, a high-performance FT-NMR-based screening system that delivers rapid and cost-effective quantitative targeted and non-targeted statistical analyses of wine, is now available from Bruker. The system features a large number of parameters delivered within a single, completely automated, push-button analysis with minimal sample preparation. Quantification of 25 relevant components is delivered on one measurement and, in addition, both quality and safety are assessed by non-targeted screening. The transferability of the method, based on standard operation procedures, guarantees identical results across different analysis laboratories and, due to its self-learning nature, the solution will further increase its capabilities as new wine analyses are integrated on a global basis.
Laser Components has introduced the LabSource series of benchtop laser sources manufactured by PD-LD with Volume Bragg Grating stabilised laser diodes to its list of products. Two models are available, the LS-1 with a single volume Bragg grating laser diode and LS-2 featuring two stabilised sources. The dual wavelength functionality of the LS-2 enables use in a variety of tasks including SERDS, which involves two Raman spectra formed from closely matching but different excitation wavelengths allowing the offset of background fluorescence, resulting in improvement in the identification and measurement of organic and biological samples and in security industries where fluorescence is widespread.
A new line of compact fibre-optic Raman probes has been introduced by FiberTech Optica. Combining the company’s knowledge in optics, spectroscopy and manufacturing of precision fibre assemblies, the probes feature an optical configuration designed to enhance both the throughput and the quality of collected Raman spectra.

P&P Optica has announced the release of Iris, a new suite of data analysis software products aimed at improving the usability of spectroscopic instruments. The software is available for the company’s spectroscopy products as well as other spectroscopic platforms. It delivers data processing techniques that previously required complex scripting and mathematical processing and makes those user requirements available in an intuitive visual interface. Features include automatic calibration, aberration correction, automatic channel detection, automatic peak detection and hyperspectral data set creation.
BioDrop, a microvolume cuvette from BioDrop, provides a robust and affordable approach to low volume spectroscopy. Its patent-pending design has the same dimensions as a conventional cuvette but is manufactured in two halves that are held together using two magnets. The precision machining ensures that the path length is accurate and its simple optical layout provides high-energy throughput ensuring accurate measurements over a wide dynamic range and only one path length is required for most experiments. It is easy to use, is robust enough to withstand the knocks and falls commonplace in laboratories and its ergonomic design makes it easy to handle, even with wet gloves. Available in 0.5 mm or 0.125 mm path lengths, it can be used to perform UV/vis spectroscopy on sample volumes as low as 1 µL, making it suitable for life scientists measureming DNA, RNA and protein samples.
Cyto-Lite, from Mad City Labs and distributed by Elliot Scientific, is a new illumination source that outputs blue, green and red laser light through a single fibre. The key wavelengths are 405 nm, 532 nm and 640 nm with the system providing complete control over each laser line via a single USB interface and the supplied software. The controller and software streamlines the user interface and allows the characteristics of each laser line to be independently controlled in constant current feedback or constant optical power feedback modes. The on-board DDS sine wave generator and internal 16-bit DAC allow for the modulation and amplitude of each laser line waveform. Low noise operation is achieved by three independent linear regulator power supplies and filtering on each laser line further minimises electronic noise. Robust and safe operation is achieved through multiple layers of laser line protection. Watchdog circuitry maintains stable power supply operation and each laser line has overcurrent protection circuitry.
The NSC1105 from New Imaging Technology is a 1.3 MPixel WDR sensor with a 10.6 µm pixel size, providing a dynamic range of more than 140 dB in a single frame time. Its Native Wide Dynamic Range technology means that it does not require any setting or exposure time control and provides a useful image whatever the illumination conditions. It also benefits from an extended spectral response in the IR range and good low light sensitivity. It is available with the company’s proprietary package which allows easy integration into PCB cards in socket or SMT mounting.
ABB has introduced the MB-Rx in situ reaction monitor for research laboratories and pilot plants in the chemical, petrochemical, pharmaceutical and biopharmaceutical industries. It is a plug-and-play solution designed around the key concepts of analytical performance, reliability and simplicity. The robust analyser provides real-time insight into chemical reaction dynamics. Key parameters such as kinetics over different phases, reagent consumption and the synthesis of products and by-products can be assessed in real time. Features include a Hastelloy ATR probe, an intuitive software interface, a compact footprint which allows it to fit inside crowded fume hoods, it is virtually maintenance-free and it does not use hygroscopic optics or a cryogenic detector.
To address the increasing demand for reliable checking of critical amounts of residual pesticides in foods, feed additives and veterinary drugs, Shimadzu has released their GC/MS Method Package, Version 2 for Residual Pesticides in Foods. It has been developed to improve the speed and efficiency of using GC/MS to analyse different residual pesticides by providing simpler inspection methods and batch analysis of multiple component samples, covering almost all pesticides that can be analysed by GC/MS technology. The new method package features a CD-ROM which contains method files which have been pre-registered with optimised analytical conditions, compound information, including retention indices, report format files, tuning files and an identification support tool. The package also includes an instruction manual and a pack of five glass inserts.
Ionicon has introduced the new PTR-QMS 500 series of on-line mass spectrometers, based on proton transfer reaction mass spectrometry, for VOC analysis. The high-sensitivity PTR-QMS and the PTR-QMS 500 are the successors to the high-sensitivity PTR-MS and standard PTR-MS. Improvements to the new series include a reduction in the size and weight of the instruments but with improved maintainability. A touchscreen display is now common to all instruments, a new heating chamber layout which is easier to access is implemented and new control electronics which are fully software-controlled are available as well as more interfaces (I/Os). The main feature, however, is the new ultra-pure ion sources that delivers a precursor ion intensity enabling the high-sensitivity PTR-QMS 500 to continuously quantify VOCs in the lowestpossible concentrations.
Agilent Technologies has launched the 8800 triple quadrupole ICP-MS which offers improved performance over a single quadrupole instrument and provides MS/MS operation for controlled and consistent interference removal in reaction mode.
