The aurora Elite is a new ultrasensitive Inductively Coupled Plasma Mass Spectrometer (ICP-MS) that complements the now updated workhorse aurora M90 ICP-MS for routine laboratory analysis. The aurora Elite boasts a host of performance enhancements and new features, with unprecedented 1.5 gigahertz per parts per million (1.5 GHz/ppm) sensitivity for precise and accurate quantification at single-digit ppt levels and below, which makes the aurora Elite the most sensitive ICP-MS instrument on the market. The lowest oxide ratios using its patented turner-interlaced coils ensures robust plasma conditions for complete matrix decomposition, all without the requirement of a plasma shield or guard electrode. The combination of the aurora Elite's high sensitivity with the all-digital detector delivers excellent results for isotope ratio determinations of low concentrations and for large ratios, and this is true for liquids and solids.


The AccuTOF-GCv 4G features the highest sensitivity (S/N > 100 at OFN 1 pg/μL) of any time-of-flight Gas Chromatography Mass Spectrometer commercially available. High resolution and mass accuracy allow for rapid elemental composition determination and target compound identification. The AccuTOF-GCv 4G combines high-speed acquisition of 50 averaged spectra per second with high mass resolving power of 8,000 FWHM and mass accuracy of 4 ppm or better to deliver high-resolution, accurate mass spectra with full mass range sensitivity for both qualitative and quantitative analysis. With a fast analog-to-digital converter providing high linear dynamic range, the AccuTOF-GCv 4G is perfectly suited to analyzing complex mixtures of true unknowns—even at low concentrations. The AccuTOF-GCv 4G is designed for optimum throughput, operation, and uptime. An optional combination EI/FI/FD ion source eliminates the need for source exchange for these experiments. Gas chromatography/field ionization can also be used to characterize samples that would be difficult to analyze by any other technique.


The next generation of the Chromeleon chromatography data system (CDS) supports mass spectrometry along with mainstream front-end separation techniques in the same software package. Thermo Scientific Dionex Chromeleon 7.2 CDS bridges the gap between gas, liquid, or ion chromatography and mass spectrometry to offer enterprise-wide gains in laboratory productivity. Major benefits of Chromeleon 7.2 CDS include: chromatography and mass spectrometry (MS) quantitiation workflows can be streamlined on a single software platform; Chromeleon 7.2 CDS's suite of automation tools, including Cobra detection algorithm, SmartPeaks integration assistant, and linking panes are designed to reduce review time and data processing; a new consolidated report function easily generates summaries of very large data sets to facilitate interpretation of results; and seamless integration of the CDS with LIMS and SDMS infrastructure can enable a paperless lab. The Chromeleon 7 platform architecture is designed to accommodate future upgrades, and eWorkflows automate many routine tasks.


The LCMS-8040 triple quadrupole mass spectrometer combines newly improved ion optics and collision cell technology with proprietary ultrafast technologies. This significantly expands the application range and ensures high-sensitivity, high throughput analysis at lower levels of detection. The LCMS-8040 incorporates newly improved ion optics (UF-LensTM), which integrate two multipole RF ion guides, and UFsweeper II collision cell technology to provide higher multiple reaction monitoring (MRM) sensitivity. A fivefold increase in sensitivity (reserpine, S/N ratio) has been achieved by improving ion focusing and minimizing ion losses between multipole lenses. These improvements also yield higher sensitivity for scan mode measurements. The LCMS-8040 achieves MRM transition speeds up to 555 MRMs per second with UFsweeper II technology, which features high-speed ion transport technology that maintains sensitivity and suppresses crosstalk. In addition, the LCMS-8040 features the world's fastest polarity switching at 15 msec and a high-speed scanning rate of 15,000 u/sec for maximum analytical throughput.


Quality Control Reference Materials (QCRMs) and Certified Containers have been added to Water's Analytical Standards and Reagents product group. Specifically designed for Waters instruments, new Quality Control Reference Materials are the simplest and fastest way to understand a chromatography or mass spectrometry system's health while ensuring repeatable performances. The Certified Containers for solvents and mobile phases are uniquely processed and treated to prevent extraneous peaks and baseline noise. By integrating these products, researchers can see improved data acceptance. Furthermore, by eliminating the need to mix and formulate standards and the unknown quality of mobile phase and solvent containers, researchers will have more time for scientific problem solving. Analytical Standards and Reagents can be seamlessly integrated into the analytical process, providing reliable results from all Waters columns brands. QCRMs and Certified Containers give confidence in the health of the system and increase productivity by reducing repeat runs.
