18 Environmental Analysis Revolutionary New Evaporator Technology Accelerates Safe Solvent Removal...
Developed in response to users requiring an evaporator that could quickly process large volumes of solvent without supervision, the Rocket Evaporator from Genevac (UK) has been designed to dry or concentrate as many as six flasks (each containing up to 450ml solvent) five times faster than conventional 'intelligent' evaporators. Using a Rocket Evaporator, users are able to focus on other tasks confident that they will achieve perfect, reproducible results every time. To achieve the dual goals of very fast evaporation, with very precise temperature control to protect valuable samples, the Rocket Evaporator uses a patented new drying technology which uses low temperature steam to directly heat the sample flasks. By pulling a vacuum on the samples, solvent(s) boil at a low temperature, which is determined by the pressure. Genevac's patented Dri-Pure®
technology further ensures
sample integrity by eliminating solvent bumping that can lead to cross contamination. The new Rocket Evaporator sets a new benchmark for ease-of-use - simply highlight the desired evaporation method using the right hand knob, and press start. New methods can be uploaded via the USB key, and data downloaded in the same way. Offering true unattended operation capability the Rocket Evaporator requires no training, even a beginner can competently use the system in less than 5 minutes. Two styles of flask are available for use with the Rocket Evaporator, a simple flask for drying or concentrating, and a SampleGenieTM style flask, which enables a large volume sample to be concentrated directly into a small vial. A 2-stage cold trap built into the Rocket Evaporator, provides very high levels of solvent recovery, even with volatile organic solvents. The 3-litre cold trap auto drains under the control of the evaporator to ensure that optimal solvent recovery is maintained, no matter what mix of solvents is being used.
Requiring no peripherals for operation the compact Rocket Evaporator fits neatly onto a laboratory bench or into a fume hood. All key components on the robust and reliable system are user serviceable ensuring a low the cost of ownership.
Reader Reply Card no 61 LC-MS/MS Solution Used to Detect Melamine
Thermo Fisher Scientific (USA) announce the availability of a method to detect melamine and cyanuric acid in food matrices. The method uses Thermo Scientific instrumentation for liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) systems, and is published in the U.S. FDA’s Laboratory Information Bulletin No. 4396, May 2007. Melamine is an industrial chemical used in the manufacturing of plastics, flame retardants and other products. Recent news coverage about the presence of melamine in infant formula, cookies and candy has once again raised public concern about the chemical in the food supply chain for both animals and humans. This latest finding comes roughly one year after the announced presence of melamine and cyanuric acid in pet food. The LC-MS/MS method utilizes the Thermo Scientific TSQ Quantum™ triple quadrupole mass spectrometer coupled to
a Thermo Scientific Surveyor™ MS pump and autosampler. Thermo Scientific Xcalibur™ data system software was used to acquire and analyze the data. Thermo Fisher Scientific has also published a related application note (Thermo Scientific Application Note 424 – May 2008), “Analysis of Melamine and Cyanuric Acid in Food Matrices by LC-MS/MS.” This application was developed on the TSQ Quantum Ultra in collaboration with the National Center for Food Safety and Technology at the Illinois Institute of Technology, Chicago, Illinois. Currently this method is being used as a reference by the labs under Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) in China to develop an LC-MS/MS method using TSQ Quantum systems for the detection of melamine in milk and infant formula. The Thermo Scientific TSQ Quantum triple quadrupole system is the only instrument that enables highly-selective reaction monitoring (H-SRM), which facilitates the quick and efficient analysis of complex samples such as food matrices and animal tissue. Additionally, the Thermo Scientific solution, when coupled to TurboFlow technology, has the advantage of providing a total solution from on-line sample preparation to data analysis, saving scientists and regulatory agencies valuable time.

New Person-Portable GC/MS for Rapid Analysis of Toxic Chemicals in the Field
Inficon (USA) introduces the new HAPSITE ER, its next generation of the only person-portable GC/MS for immediate, on-site investigation and analysis of volatile organic compounds (VOCs) in air, water and soil at parts per trillion (ppt) for most analytes. This field-proven chemical identification system gives even faster results for rapid decision-making, providing highly accurate chemical separation and identification in less then ten minutes. Powered by intuitive, state-of-the-art software, HAPSITE ER combines new features, such as a shorter run time and low consumables usage, with easy-to-use-operation. Its bright, color touch screen displays complete analysis results, including chromatograms, spectra, library search results and quantitative data – all clearly visible in daylight or darkness.
Instant air analysis can be conducted using only the MS (mass spectrometer) and by-passing the GC column (gas chromatograph). HAPSITE ER automatically determines correct sampling distance from unknown chemicals to provide the most reliable, rapid, real-time screening of air samples, where higher concentrations of VOCs are encountered (>1 PPM), adding operational versatility and enhancing
the applications range.
For the most demanding environments, the rugged HAPSITE ER provides cost-efficient, dependable field analysis offering sample inlet options for different sample matrices and pre-installed operating methods for each sampling device, utilizing AMDIS and NIST search tools for identifying unknowns. Application specific methods can also be developed, and quantification can be established for specific analytes.
HAPSITE ER is specifically designed for on-site pollution investigations, site remediation studies or process monitoring and control, disaster scene investigation and mitigation, and security applications.

Emerson Process Management’s (USA) Smart Wireless field network is automating inventory management by monitoring levels in fourteen tanks at Technochem Environmental Complex Pte Ltd (TEC) in Singapore. TEC provides treatment, incineration and distillation services for chemical wastes generated by pharmaceutical and petrochemical companies. In addition to delivering continuous level measurements from storage and process tanks, some of the fourteen Rosemount® wireless pressure transmitters are moved from place to place to aid in troubleshooting and new process development in TEC’s continuous improvement culture. Because the wireless instruments are not fixed in position by wiring, Incineration Manager Jan Huijben takes advantage of their mobility and the fact that they can be reinstalled in a matter of minutes.
“If I see a problem in some part of our process, it is fairly simple for me to take a pressure transmitter and move it elsewhere,” Huijben said. “I can often determine what’s going on in just five minutes, address the issue and quickly return the transmitter to its original application. The flexibility of Emerson’s self-organising wireless technology makes it much easier to troubleshoot problems as well as evaluate new applications.”
When Huijben arrived at Technochem just over a year ago, an accurate tank level measurement system was needed along with an automated method of moving that data into a computer database. In addition to tracking and managing inventories, documentation was necessary to schedule incoming customer delivery and give the status of their orders, including assurance that their chemical wastes had been treated and destroyed. Wired devices were considered initially, but the high cost of wiring, even in this relatively small complex, was a drawback. When the new wireless technology was introduced to Technochem management, they were impressed by the ease of installation, the speed with which transmitters could be up and communicating from essentially any spot in the complex, the reliability of the self- organising network, and the inherent flexibility and mobility of the wireless sensors.
The benefits have been apparent since the installation in April 2008 of wireless pressure transmitters to report on tank levels, including elimination of “clipboard rounds”, more accurate real-time data for process efficiency, documentation to verify that specific chemical wastes have been destroyed, and access to the data via the company network. When management personnel are at another site, they can view the process data and order changes if necessary. Electronic connection of select data for customers is being developed.
