Particle Measuring System (USA) Airborne Molecular Contamination (AMC) monitor, the AirSentry II, was designed for high sensitivity, speed, and low cost. Building upon the original AirSentry-IMS system, the new Ion Mobility Spectrometry (IMS) cell provides ppt sensitivity, fast response, and increased selectivity. Continuous coverage of a critical monitoring point and a central software platform allow for easy data acquisition and analysis.
Current monitoring techniques, most evolving from a strategy of adapting old technology to contamination applications, are proving inadequate as critical dimensions shrink and lithography tools increase their exposure energy. Problem such as lack of time resolution, sample transport contamination, and insufficient sensitivity have become increasingly problematic. Working to resolve these inadequacies, the AirSentry II continuously monitors a critical point with the highest sensitivity offered in a low cost, point-of-use AMC monitor.

The Pulsar Instrument – Ultra Simple Sound Level Meter
Combining computer technology with ultra simple operation, the Pulsar Instruments (UK) sound level meter model 14 is an entry level instrument intended to be used primarily for factory surveys to enable employers to meet the “Noise at Work” regulations at the lowest possible cost.
As well as simplicity in operation, particular attention has been paid to the display and a new design of LCD has been used with very high legibility in all light conditions. The unit has not only the A-frequency-weighting required by the EU directive, but as well, C- Frequency-weighting, both with F-time-weighting or what was traditionally called ‘Fast response’.
The intent of the model 14 is to carry out an initial survey of factories and other workplace where the noise levels are not expected to be very high. If during and initial survey, no noise level is found that is over say 75dBA, no worker can be exposed to dangerous noise levels and the employer can be confident that he is fully compliant with the current regulations. Even if one or more slightly higher levels are found, these can be avoided or a more complex Leq meter can be used to quantify the average level, or a Personal Sound Exposure meter such as the Pulsar Model 22 ‘doseBadge’ used to measure the noise exposure of individual workers. A high sensitivity range is also fitted, going down to 35 decibels to allow noise to be checked at the boundary of any premises to ensure that noise is not escaping from a workplace.
A major problem with measuring noise accurately for the purposes of the EU directive is the presence of many ultra low cost units, intended for hi-fi. That can be bought from many non-professional retail outlets, but these are simply not suitable for measuring industrial noise as they have not been checked for accuracy and in general cannot be officially approved. Model 14 is normally supplied as a kit including a calibrator – mandated by the Directive as well as the operating manual etc, housed in a carrying pouch and fully complies with the latest International standards IEC 61672 at Class 2 level as well as the older IEC 60651 Type 2.lt therefore offers the lowest cost fully compliant meter available on the European market.
Pulsar Instruments plc have been manufacturing high quality sound measuring equipment since 1969, in the USA and Uk and offer their standard 2 – year warranty with model 14 that can be extended at no cost, when the instrument is regularly calibrated.

Remote Monitoring in Hazardous Areas via GPRS
R.STAHL's (Germany) 9719-type GSM/GPRS modem, which combines a robust design with state-of-the-art technology and easy installation, allows users to fully benefit from the advantages of GSM/GPRS data communication in zone 1 or 2 hazardous areas for the first time. Designed as a quad-band device, the 9719 modem is suitable for use in process plants in virtually all world regions.
Thanks to IP67 protection, the unit can be installed in outdoor areas without an additional enclosure. The SIM card holder and the antenna interface are instrinsically safe (Ex i), thus enabling users to safely change SIM card or install antennas in hazardous areas. The modem is directly connected to a PLC, an industrial PC or an OpenHMI via an RS232 interface. It comes with a wide range of functions which can be easily controlled via the same AT command set as conventional modems for standard industry applications. An LED display continuously indicates the modem status.
GSM/GPRS data communication has many uses in the process industry, e.g. monitoring unmanned pumping stations, remote tank farms or machines such as centrifuges or compressors. Users benefit not only from the fact that this communication technology is ideally suited for mobile applications : additionally, GPRS allows for the establishment of cost-efficient data connections which inform users about the status of plants or the fill level of tanks. Communication is thereby rendered independent from the infrastructure installed on location, and unlike WLAN technology, no longer requires users to implement their own radio network. R.STAHL supplies two versions of the modem, one integrated into a stainless steel enclosure, the other featuring a GRP enclosure. This design facalitates installation in the field.

It's the Environment, Stupid
It was the year of the Copenhagen conference and the "climategate" affair, but there was more to 2009 than these political brouhahas: here are 10 to remember.
1. How to survive the coming century Alligators basking off the English coast; a vast Brazilian desert; the mythical lost cities of Saigon, New Orleans, Venice and Mumbai; and 90 per cent of humanity vanished. Welcome to a world warmed by 4 °C.
2. 1709 : The year that Europe froze One winter in the early 18th century, it was so cold animals died in their barns, travellers froze to death, and even the Mediterranean iced over. It was Europe's coldest spell for the past 500 years.
3. One last chance to save mankind James Lovelock, originator of the Gaia theory, thinks climate change will wipe out most of us this century – but there may be one way to save ourselves.
4. Meet the amphibian only its mother could love A bug-eyed salamander that looks like ET and a see-through frog were among the weirder species discovered by biologists in a far-flung corner of Ecuador.
5. Supervolcano may be brewing beneath Mount St Helens A sneak peek beneath Washington state's simmering volcano suggests it may be connected to an extraordinarily large zone of semi-molten rock, which could feed a giant eruption.
6. Sea level rise: It's worse than we thought In its 2007 report, the Intergovernmental Panel on Climate Change forecast a sea-level rise of between 19 and 59 centimetres by 2100. Even before it was released, the report was outdated, and the bad news is that there is a growing consensus that its estimates were wildly optimistic. So just how high will the ocean go?
7. Post-human Earth: How the planet will recover from us If our civilisation collapses, what will happen to the Earth itself? The best way to work that out is to look back at its past.
8. Giant crack in Africa formed in just days A split in the Earth's crust ripped open in a matter of days in 2005, a new study suggested. It could be the forerunner to a new ocean.
9. Ice on fire: The next fossil fuel Methane trapped in ice under the ocean and permafrost on land could fuel the world for hundreds of years – but there's an explosive snag.
10. Earth's coastlines after sea-level rise, 4000 AD Even if we could keep the atmosphere as it is today, sea levels would still rise by 25 metres. The good news is that there's a limit on how fast that rise can take place.

XRF Analyzer with Large Area Drift Detector
Thermo Fisher Scientific (USA) introduce Thermo Scientific Niton XL3t Series with geometrically optimized large area drift detector (GOLDD) technology. The Niton analyzer's ground breaking GOLDD technology delivers improvements in light element detection, overall sensitivity and measurement times - as much as 10 times faster than conventional Si-PIN detectors, and up to three times more precise than conventional smaller, silicon drift detectors.
Thermo Fisher Scientific was able to surpass the performance of conventional Si-PIN and SDD detectors by combining the award-winning Niton XL3t 50 kV, 2-watt X-ray tube, closely optimized geometry and patented signal processing hardware and software. When combined with the company's proprietary large area drift detector, it creates GOLDD technology, delivering superior performance in the form of faster analysis and lower detection limits. Furthermore, this innovation allows light element detection of magnesium, aluminum, silicon, phosphorus and sulphur without helium or vacuum purging, a significant productivity and user benefit.
" The Niton XL3t with GOLDD technology brings true lab-quality performance to a hand held XRF analyzer," said Bob Wopperer, director of business development for portable analyzer products within Thermo Fisher Scientific. " The product is easy to use, delivers fast analysis, is extremely accurate, and can measure light elements without helium or vacuum assistance. These features make it the ideal, multi-purpose tool for analyzing metal alloys, carrying out mining exploration and mapping, detection soil contaminants, or screening toys, electronics and other consumer goods for prohibited substances."
For example, the Niton XL3t GOLDD is the definitive tool for scrap metal recycling, making it easier to sort aluminum, titanium and bronze alloys, as well as achieving superior performance for tramp and trace element analysis. And in mining exploration, the instruments low detection limits are designed to allow geologist to identify anomalies at or below the averages naturally found in the earth's crust, something previously not possible with hand held XRF

Next Generation Capillary Electrophoresis System Featuring 10x Superior Sensitivity
Agilent Technologies (Asia) introduced its next generation Agilent 7100 Capillary Electrophoresis (CE) System, providing at least 10 times more sensitivity than any other commercial CE instrument.
"We consider electrophoresis to be one of our core technologies and are seeing strong interest in CE in a number of areas, such as new biological drug QA/QC, environmental analysis, food safety and life sciences," said Nitin Sood, General Manager of Agilent's Electrophoresis business. " Used in stand alone mode, as the separations component of a CE/MS or as a complementary, orthogonal technology to LC, Agilent's new 7100 CE system brings unprecedented HPLC-like sensitivity to a wide range of analytical challenges."
CE is also attracting attention because the technique uses very small amounts of solvent. The new 7100 system also requires 25 percent less bench space, weighs 30 percent less than its predecessor and uses less power. The superior sensitivity is a result of a new detector used in combination with proprietary extended light path capillaries or a high-sensitivity cell. The Agilent 7100 is 10-20 times more sensitive than other CE instruments.
