New on the market
Go with the flow
Wyatt Technology of Santa Barbara, California, US, has introduced the Eclipse separation as an alternative to conventional column chromatography, based on asymmetrical flow field-flow fractionation. Separation is achieved by a cross-flow permeating through the bottom wall, while the sample is transported by the longitudinal flow towards the channel outlet and detectors.
As well as enhanced resolution and peak height, consumption of eluent and analysis time are also reduced. The smaller channel is easier to handle for membrane replacement, and has faster equilibration time, resulting in less down time and increased sample throughput.
The Eclipse is ideal for use in molecular biology, nanotechnology, and environmental analyses, including the separation and characterisation of proteins and aggregates, liposomes, emulsions, antibodies, viral particles and polysaccharides.
Spectrometer in your hand
The USB4000 miniature fibre optic spectrometer from Ocean Optics of Dunedin, Florida, US, is small enough to be held in the palm of a hand but can perform many spectroscopic tasks. It features a 3648-element linear CCD array for substantially increased signal-to-noise, and enhanced 16-bit electronics for controlling the spectrometer and accessories.
With a choice of 14 gratings and six slits, the USB4000 can be configured for many absorbance, reflection and emission applications.
It features five triggering options, is responsive from 200-1100 nanometres and has an integration time of 10 microseconds, enabling the measurement of transient events such as laser pulses.
Columns par excellence
Waters of Milford, Massachusetts, US, has introduced the Acquity UPLC HSS T3 column, with new high-strength 1.8 m m silica particles, aimed at separating small, water-soluble, polar organic molecules via reversed phase UPLC (ultra performance liquid chromatography) technology.
Waters has also introduced the Atlantis T3 HPLC (high performance liquid chromatography) column for retaining polar compounds by reversed-phase HPLC.
The T3 bonding used in the columns combines longer column lifetimes at low pH and improved peak shape for amine-containing bases at pH 7 with superior polar compound retention and 100 per cent aqueous compatibility.
Load your reactions and go
CEM Microwave Technology from Buckingham, UK, has launched the Explorer S-Class microwave synthesis system which offers a choice of 48, 72 or 96 positions. These can accommodate 4ml, 10ml or 35ml vials and an intelligent rack system allows the autosampler to recognise which size racks are placed on the deck and where.
The system then automatically configures the deck map using the new Synergy software. Explorer allows the user to run different sized vials on the same deck in any rack combination.
Bruker Biospin has launched the EMXplus, an EPR (electron paramagnetic resonance) spectrometer.
The EMXplus system offers full 24-bit resolution, and is sweep-time independent. Also, the signal channel and field controller combination work together to provide practically unlimited resolution in both axes: field and signal intensity.
Applications include: kinetics of radical reactions, polymerization reactions, spin trapping, organometallic compounds, catalysts and biradicals and triplet states of molecules.
Analysing difficult samples
Shimadzu UK of Milton Keynes, has introduced the GCMS-QP2010 Plus for characterisation of complex organic mixtures in toxicology, environmental monitoring and food and flavor analysis.
The instrument has a mass range of 1.5 to 1090 Daltons and sensitivity of 1pg for octafluoronaphthalene in electron impact and negative chemical ionisation modes.
A new and improved ion source gives more uniform temperature control, a new filament that resists deformity, and an expanded temperature range of 100 to 300°C.
Hach Ultra, headquartered in Geneva, Switzerland, has released the Orbisphere G1100 luminescent oxygen sensor for detecting ppb traces of dissolved oxygen.
The sensor can be used in power plants measuring dissolved oxygen in all-volatile treatment (AVT) or oxygenated treatment (OT) environments.
Tubes for pumps
SPETEC of Erding, Germany, has started producing tubes for peristaltic pumps and continuous flow systems, made from PVC, silicone, Santoprene and Fluor Rubber (comparable to Viton).
The tubes are offered in different configurations, with two or three bridges depending on application. The tubes have an inner diameter from 0.12mm to 3.3mm .
Detector on low power
Hamamatsu Photonics of Welwyn Garden City, UK, has introduced the H9858 series of miniature photomultiplier tube modules, working from the ultraviolet through visible to the infrared.
The H9858 series can operate for in excess of 1000 hours from two AA batteries, making them ideal for portable instrumentation applications.
