(1) Bruker BioSpin has introduced an integrated nuclear magnetic resonance spectrometer called the Avance III NanoBay. It incorporates the company's Avance III NMR instrument in a compact enclosure for use with 300- or 400-MHz magnets. Despite its small size, the system has full capabilities and user-friendly software, including Japanese and Mandarin Chinese graphical user interfaces. The system can handle industrial applications ranging from high-throughput screening in analytical chemistry to structure verification in drug discovery. In academia, it could be used in research or instruction.
The 454 Life Sciences division of Roche Applied Science has launched new products for the ultra-high-throughput Genome Sequencer FLX (GS FLX) system. Two new plate formats, a "short read" plate for 100 base pairs and a "long read" for 250-300 base pairs, provide researchers with greater flexibility and should decrease the cost per run, the company says. Also, 454 Life Sciences has upgraded software for GS FLX to incorporate Sanger sequencing reads and to integrate GS FLX data with third-party software. Separately, Applied Biosystems (ABI) has announced a software development community initiative to help independent software vendors build bioinformatics applications for DNA sequencing. ABI will make sample data sets, data file formats, and data conversion tools for its SOLiD System DNA-sequencing platform available.
On-line reaction monitoring is used often in pilot plants, and high-performance liquid chromatography is a common analytical tool, but the combination is seldom found at the lab bench. To create a convenient research tool, Merck process scientists and collaborators at Eksigent Technologies have developed a compact and mobile HPLC unit for on-line reaction monitoring in the lab (Org. Process Res. Dev., DOI: 10.1021/op7000854). Their AliquotMobile system consists of a cart-mounted microfluidic ExpressLC-100 HPLC instrument and a tethered, automated sampling and dilution module. The aliquot size is a few microliters, the aliquot dilution is adjustable, and sampling rates range upward from a minimum of every 4 minutes. Reaction quenching is also possible. Data for ongoing or completed studies can be viewed to monitor reaction progress or kinetics.
Bruker AXS has launched the SMART X2S (crystal-to-structure) benchtop X-ray crystallography system. The instrument is designed for chemists with no special training in crystallography to use in their own labs. Analysis is automated, from sample loading and alignment to structure solution. The system weighs less than 70 kg and requires 0.5 kW of standard AC power.
Rigaku has introduced the Ultima IV for general-purpose X-ray diffraction (XRD) analysis in materials science, semiconductors, and nanotechnology R&D. The instrument, half the size of conventional XRD units, has a new high-speed detector and cross-beam optics. In addition, Rigaku has added two charge-coupled device detectors to its crystallography product line: Saturn 944+, optimized for macromolecules, and 724+ for small molecules.
Thermo Fisher Scientific has introduced the ARL 9900 Series X-ray WorkStation(2), which integrates X-ray fluorescence (XRF) and diffraction analysis in one unit. The combination allows complete elemental and structural analysis with a single instrument. Analysis is fully automated in either XRF or XRD mode. Data from either method can be used for processing data from the other.
Thermo Fisher Scientific is offering a kit to couple gas chromatography and its ELEMENT 2 and ELEMENT XR high-resolution inductively coupled plasma mass spectrometers (ICP-MS). The kits are designed to enable scientists to use a magnetic sector ICP-MS as a GC detector and expand the capabilities of ICP-MS analysis of volatile compounds. The kit is intended to allow scientists in the environmental, clinical, and biological markets to detect and quantify volatile compounds containing elements such as sulfur, tin, phosphorus, mercury, and bromine.
