AirClean® Systems PowderSafe™ Type B Enclosures
AirClean® Systems PowderSafe™ Type B Enclosures usher in a new era of powder weighing and containment technology. PowderSafe Type B enclosures provide a controlled negative pressure HEPA-filtered environment for professionals to work with and weigh powders.
PowderSafe Type B is fabricated with polypropylene, which is a chemically resistant, high mass polymer. The innate chemical resistance of polypropylene allows users to easily clean the enclosure without the worry of degradation, while the high mass construction alleviates the threat of vibration and balance disturbance during weighing.
Exclusive to PowderSafe enclosures, HepaSafe™ technology allows the operator to safely and easily change both the prefilter and the primary HEPA filter while the enclosure remains under negative pressure. Furthermore, FlowSmooth™ technology provides even, horizontal air distribution throughout the enclosure, preventing turbulence. This laminar horizontal air movement is also key to operator protection from hazardous chemical and compounds being manipulated within the enclosure. PowderSafe has been independently tested for containment by both SafeBridge Consultants, Inc and Triangle Certification.
The AirSafe™ automatic safety controller, a standard feature on all PowderSafe enclosures, monitors and maintains proper face velocity so accurate balance readings can be ensured without turbulence or vibration. AirSafe also monitors HEPA filtration and will alert the end user if filter change is necessary. This advanced technology allows PowderSafe to be completely self-contained and self-monitored, eliminating the need for external filter boxes, ductwork, filter sampling ports, or other cumbersome parts.
PowderSafe enclosures are the most advanced and user-friendly powder weighing containment solutions available today. Each PowderSafe enclosure is shipped fully assembled and made in the USA.
For more information on PowderSafe enclosures, visit our website at www.aircleansystems.com or contact our Technical Sales Department at 919-255-3220 or 800-849-0472.

A new microextraction technique termed dispersive liquid-liquid microextraction (DLLME) was developed. DLLME is a very simple and rapid method for extraction and preconcentration of organic compounds from water samples. In this method, the appropriate mixture of extraction solvent (8.0 μL C2Cl4) and disperser solvent (1.00 mL acetone) are injected into the aqueous sample (5.00 mL) by syringe, rapidly. Therefore, cloudy solution is formed. In fact, it is consisted of fine particles of extraction solvent which is dispersed entirely into aqueous phase. After centrifuging, the fine particles of extraction solvent are sedimented in the bottom of the conical test tube (5.0 ± 0.2 μL). The performance of DLLME is illustrated with the determination of polycyclic aromatic hydrocarbons (PAHs) in water samples by using gas chromatography-flame ionization detection (GC-FID). Some important parameters, such as kind of extraction and disperser solvent and volume of them, and extraction time were investigated. Under the optimum conditions the enrichment factor ranged from 603 to 1113 and the recovery ranged from 60.3 to 111.3%. The linear range was 0.02-200 μg/L (four orders of magnitude) and limit of detection was 0.007-0.030 μg/L for most of analytes. The relative standard deviations (RSDs) for 2 μg/L of PAHs in water by using internal standard were in the range 1.4-10.2% (n = 5). The recoveries of PAHs from surface water at spiking level of 5.0 μg/L were 82.0-111.0%. The ability of DLLME technique in the extraction of other organic compounds such as organochlorine pesticides, organophosphorus pesticides and substituted benzene compounds (benzene, toluene, ethyl benzene, and xylenes) from water samples were studied. The advantages of DLLME method are simplicity of operation, rapidity, low cost, high recovery, and enrichment factor. © 2006 Elsevier B.V. All rights reserved.

Abstract
Room-temperature ionic liquids (RTILs) are solvents that may have great potential in chemical analysis. Recent surge in the number of publications/reports/books/monographs clearly indicate an increasing interest of scientific and engineering community toward these exciting and unique solvents. Consequently, a variety of analytical applications of RTILs have started to emerge. This review presents an account of some of the recent reports on RTILs in major subdisciplines of analytical chemistry. Specifically, recent literature representing the applications of RTILs in chromatography, extraction, electroanalytical chemistry, sensing, and spectrometry is reviewed. With a rapid growth in the number of publications on analytical applications of RTILs, it appears that in the near future these neoteric solvents are definitely going to be a permanent feature in analytical chemistry. © 2005 Elsevier B.V.

Carbon nanotubes (CNTs) combine in a unique way high electrical conductivity, high chemical stability and extremely high mechanical strength. These special properties of both single-wall (SW) and multi-wall (MW) CNTs have attracted the interest of many researchers in the field of electrochemical sensors. This article demonstrates the latest advances and future trends in producing, modifying, characterizing and integrating CNTs into electrochemical sensing systems. CNTs can be either used as single probes after formation in situ or even individually attached onto a proper transducing surface after synthesis. Both SWCNTs and MWCNTs can be used to modify several electrode surfaces in either vertically oriented "nanotube forests" or even a non-oriented way. They can be also used in sensors after mixing them with a polymer matrix to form CNT composites. We discuss novel applications of CNTs in electrochemical sensors, including enzyme-based biosensors, DNA sensors and immunosensors, and propose future challenges and applications. © 2005 Elsevier Ltd.

The electrochemistry of dopamine (DA) was studied by cyclic voltammetry at a glassy carbon electrode modified by a gel containing multi-walled carbon nanotubes (MWNTs) and room-temperature ionic liquid of 1-octyl-3- methylimidazolium hexafluorophosphate (OMIMPF6). The thickness of gel on the surface of the electrode has to be controlled carefully because the charging currents increase with the modified layer being thicker. The anodic peaks of DA, ascorbic acid (AA) and uric acid (UA) in their mixture can be well separated since the peak potential of AA is shifted to more negative values, while that of UA is shifted to more positive values due to the modified electrode. At pH 7.08 the three peaks are separated ca. 0.20 and 0.15 V, respectively; hence DA can be determined in the presence of UA and more than 100 times excess of AA. Under optimum conditions linear calibration graphs were obtained over the DA concentration range 1.0 × 10-6 to 1.0 × 10-4 M. The detection limit of the current technique was found to be 1.0 × 10-7 M based on the signal-to-noise ratio of 3. The modified electrode has been successfully applied for the assay of DA in human blood serum. This work provides a simple and easy approach to selectively detect dopamine in the presence of ascorbic acid and uric acid. © 2004 Elsevier B.V. All rights reserved.

Video Demonstrates Benefits of Controlled Nucleation...
SP Scientific has broadcast a new video that demonstrates how ControLyo ™ Nucleation On-demand Technology can be used to control the nucleation of a product during freezing, such that the entire product nucleates at the same time and in the same way.
Using an example of freeze drying samples in vials the video (http://www.spscientific.com/) illustrates how ControLyo™ Technology enables the freezing step to be much more repeatable and allows potentially greater control over cycle optimization.
SP Scientific has signed a license agreement with Praxair, Inc. to utilize Praxair's ControLyo™ Nucleation On-demand Technology, which provides pharmaceutical and biotechnology companies with precise control over the freeze-drying process for drug developmental efforts.
This breakthrough technology was developed to specifically control the freezing step of lyophilization. Freeze drying (also known as lyophilization) is a method of drying products whereby the material is frozen (made chemically inactive) and then placed under vacuum while energy, in the form of heat, is added so that the ice sublimates (goes directly from a solid to a vapour without entering the liquid stage) thus rendering the product stable at elevated temperatures. Until now, the freezing step of lyophilization was uncontrolled due to the random nature of the nucleation or crystal-forming process. Praxair's new ControLyo™ technology now makes nucleation control a reality by regulating the nucleation temperature to within 1°C of its freezing point. The results are improved product uniformity, quality and yield.
For further information please contact SP Scientific on +1-845-255-5000 / +44-1473-240000 or email ControLyoInside@SPScientific.com.

Mass Frontier 7.0 software features an enhanced Fragment Ion Search (FISh) screening tool, which includes automatic localization of the site of biotransformation through color coding applied to fragments common to the parent compound and its related component. FISh is a novel tool for the screening of structurally similar compounds based on the fragmentation pattern of the parent compound acquired either by theoretical fragment prediction or experimental MSn spectral trees. It utilizes the compound structure to filter out the vast majority of matrix-related background ions. It also has a new comprehensive user interface allowing flexible entry of processing parameters in a single window.
“Mass Frontier 7.0 software has many unique features that are not in any other software program,” states lead beta tester, Ji Ma, Ph.D., Principle Scientist from Amgen. “Structural elucidation is a time consuming and labor intensive process to manually interpret spectra; however Mass Frontier 7.0 software with its unique new features has significantly improved our workflow.”
Mass Frontier 7.0 software also offers a number of enhancements designed to increase productivity and improve user experience. Users can, for example, save work in progress and processing methods to streamline metabolite identification and structural elucidation workflow so there is no loss of data. In addition, component comparison and de novo structural elucidation can be done using the innovative spectral tree comparison tool with a new proprietary algorithm and visualization options. New comprehensive and customizable reporting tools provide the user with the capability to create reports in their chosen format.
Mass Frontier 7.0 software is enhanced with new chemically intelligent tools that accelerate the interpretation of mass spectral data. The predictive fragmentation capabilities of the copyrighted HighChem Fragmentation LibraryTM are exclusive to the program and contain fragmentation mechanisms for small molecules collated from published literature, allowing users to quickly search thousands of entries. The library, together with twenty-four general ionization, fragmentation and rearrangement rules, serves as a knowledge base for the prediction of fragmentation pathways. In addition to the literature-based Fragmentation Library, Mass Frontier software also allows users to create their own unique libraries of customized fragmentation mechanisms, save them to the database, and apply them to predict fragments. Different groups of users can also easily share and manage their knowledge through the client-server capabilities.
“Unparalleled predictive fragmentation coupled with automatic deconvolution and annotation of MSn spectral ion trees facilitates the interpretation of mass spectral data,” also comments Ji Ma, Ph.D.
The program now includes an elemental composition check so that fragments containing unrecognized elements to the precursor ion are automatically discarded. In addition, the structures of precursor ions at various MSn stages are automatically displayed as the user browses through the spectral ion tree to facilitate the annotation of product ions. The user also has the ability to manually annotate additional peaks under the specified threshold.
Mass Frontier software complements Thermo Scientific MetWorks metabolite identification software for the study of biotransformations, MetQuest screening software for simultaneous quan/qual drug metabolism and pharmacokinetic analysis and SIEVE differential analysis software for the study of metabolomics.

Webinar - Exploring Genetic Diversity
Fluidigm Europe has announced an opportunity for scientists to learn more about how the Fluidigm Access Array™ System is being used by the US National Cancer Institute to explore genetic diversity and how to effectively implement techniques for next generation sequencing.
A recorded version of the Science magazine webinar: 'Exploring Genetic Dversity: Mapping the Genetic Landscape through Next-Generation Sequencing** prominently features results from the Fluidigm Access Array System within the presentation by Michael W Smith Ph.D, director of the Genetics and Genomics Group within the Advanced Technology Program of SAIC Frederick.
Characterizing the genetic diversity in populations can be challenging, because of the sheer number of samples needed to understand the underlying genetic variation. Using multiplexed polymerase chain reaction (PCR) along with barcoding, offers the possibility of sequencing hundreds of unique samples per run using next- generation sequencing technology. This process, known as amplicon resequencing, allows for each PCR amplicon to be sequenced individually, enabling both the identification of rare variants and the assignment of haplotypes.
The webinar** provides an overview of amplicon resequencing-based approaches, from the perspective of investigating the complexity and diversity seen in immune system genes. Three experts in the field discuss topics such as site-specific recombination reactions and cellular dysfunction, as well as how to use cutting-edge technology to discover pathways and specific patterns that impact such factors as the ability of the body to mount an immune response and somatic recombination in antibody production.
The Fluidigm Access Array integrated fluidic circuit is a unique microfluidics chip which houses thousands of nanoscale reaction chambers. The Access Array is configured to run 48 samples and 48 primer pairs simultaneously for a total of 2304 reactions. The authors describe how they evaluated and validated two protocols using the Access Array system to conduct, short and long-range capture. The short range protocol captures target lengths up to 700bp, while the long-range protocol currently captures up to 5Kb. For further information on how the Fluidigm Access Array System is enabling scientists involved with next generation sequencing to get better results faster please visit www.fluidigm.com/fields-research/next-gen-sequencing.php.
