Revolutionary Atomic Spectroscopy Instrument Runs Entirely on Air
Agilent Technologies (USA) introduces the 4100 Microwave Plasma-Atomic Emission Spectrometer, a breakthrough elemental analysis instrument that runs entirely on air.
The 4100 MP-AES fundamentally changes the way scientists conduct elemental analysis. Using a nitrogen-based plasma that runs on air, the 4100 MP-AES does not require flammable or expensive gases.
With no external cylinder connections required and no need for ongoing gas supplies, the 4100 MP-AES is ideal for any elemental analysis laboratory–especially remote sites and mobile laboratories. By eliminating the need to plumb multiple gases into the laboratory or manually transport and handle gas cylinders, the 4100 MP-AES also improves lab safety.
The MP-AES instrument from Agilent is a home run for both gold analysis and base-metal analysis,” said Bobby Joe Reichel, analytical development – Nevada Laboratory Services, Newmont Mining Corporation. “It provides superior detection limits and a vastly expanded calibration range to enable quick and easy analysis at trace levels, while eliminating the need for time- consuming dilutions of higher grade samples.”
“The Agilent 4100 MP-AES is the most significant technology advancement in atomic spectroscopy in decades,” said Philip Binns, Agilent vice president for spectroscopy products. “Agilent is changing the game in the field of elemental analysis. The 4100 MP-AES does not redefine a product category, it creates an entirely new one while offering the lowest cost of ownership for elemental analysis along with improved laboratory safety.”
Applying tried-and-true microwave technology to spectroscopy, the 4100 MP-AES delivers impressive performance as well. The magnetically excited microwave plasma source provides improved linear dynamic range, superior detection limits, and faster measurement compared with flame atomic-absorption spectroscopy.
Easy to use application-specific software applets automatically load a preset method, enabling users to start analysis without the need for method development or alignment. Minimal training is required.
Since flammable gases are no longer required, the 4100 MP-AES allows for safe, unattended multi-element overnight operation.

Portable Photosynthesis System with Enhanced Performance and Features
ADC BioScientific (UK) designers and manufactures of Plant Science research instrumentation, has introduced a portable and easy to use photosynthesis system for advanced field experimentation. The LCpro-SD is a truly portable and affordable photosynthesis system with full experimental programming and environmental control.
The LCpro-SD provides full automatic and enhanced control of the environmental
conditions within the plant leaf chamber. CO2, H2O, Temperature and PAR can now be more accurately and easily controlled than ever before. All the environmental control facilities are contained within the single compact and lightweight console.
Featuring the very latest in Infrared Gas Analysis technology, the LCpro-SD features a number of enhancements to field gas exchange performance including an extended measurement range, faster response times and less instability caused by ambient CO2 fluctuations. Weighing only 5kg, the LCpro-SD is less than half the size and weight of traditional systems. The battery operated LCpro-SD will function continually for up to 16 hours from a single charge. Sophisticated photosynthesis experiments, such as A/Ci curves and light response curves, can now be easily performed in previously impractical field locations.
The LCpro-SD features enhanced graphic display capabilities for real time experimental viewing. Data is stored on removable SD cards and can be reviewed on the graphic display and downloaded directly from the SD cards, via USB, or RS232.
An expanded range of easily interchangeable leaf chamber heads means that the LCpro-SD can be used for the largest ever variety of field applications, including a wide range of plant leaves, whole plants and a soil chamber for field soil respiration experimentation.
This powerful, yet affordable, research instrument will prove an invaluable tool in enhancing our understanding of world crop efficiency and a host of global environmental issues.

High-Precision Analysis for a Multitude of Samples
Shimadzu (Germany) has launched a new series of scanning spectrophotometers: the UV-2700, a true double beam double monochromator system and the UV-2600 single monochromator version. The new compact spectrophotometers enable high- precision spectral analysis of a wide range of samples including organic and inorganic compounds, biological samples, optical materials and photovoltaics.
The UV-2600 and UV-2700 offer “best in class” performance in stray light, photometric range and scan speed. At just 45 x 60 cm the footprint of the instruments has been decreased by 28% in comparison to the previous UV-2450 and UV-2550 models.
The UV-2700 covers a wavelength range from 185 to 900 nm and is perfect for highly sophisticated applications such as direct measurement of high density samples up to 8 absorbance units without dilution. The high performance level of the optical system is achieved with Shimadzu’s “LO-RAY-LIGH®
TIRED OF THE SAME OLD PURGE & TRAP VENDORS?
based on a new holographic method featuring highest efficiency and exceptionally low stray light.
Where the ultra-low stray light levels of the UV-2700 are not needed, the UV-2600 single monochromator version is available. Combined with the ISR-2600 Plus dual detector integrating sphere, it allows a measuring range up to 1,400 nm giving access to the determination of optical material or expanded research of photovoltaics.
