34 Environmental Analysis New On-Line Library of Searchable Chromatographic Applications
Dionex (USA) is pleased to announce that its new on-line library of searchable chromatographic applications–the D-Library–is now available on its website free of charge (registration required after introductory period).
“Search tools for locating and using applications used to be relatively basic, and did not offer the range of options that customers are looking for,” said Andreas Brunner, Product Manager for the Dionex Chromeleon®
Chromatography Data System (CDS) software. “In addition, once applications were found, it often took a long time to assess them for suitability, and to run them on an IC or LC instrument. The launch of the D-Library changes all this.”
“With our new service, users can easily search for applications using a basic text entry or by using advanced search criteria. This allows, for example, finding exactly those applications that analyse a certain component, use a column with a maximum of 3 µm particle size and 15 cm length, and have a runtime of less than 20 minutes.” The user can view the chromatogram, results, and many other details of the application and download them as a PDF file. In addition, most applications will also offer the Chromeleon software eWorkflows† or a template sequence that can be downloaded directly into Chromeleon software thus allowing users to start working with applications immediately. The application is RSS enabled for even faster access to new applications.

Debate continues on the chemical compound Bisphenol A (BPA) regarding its effects on human health and whether it requires regulation. Used in industrial activities, particularily in resins and plastics used in food and beverage packaging materials, BPA has been the subject of numerous studies, many linked to human health concerns. One study estimates there are detectable levels of BPA in more than 90% of the US population.
Reacting to this news, Canada declared Bisphenol A a hazardous substance, the American Medical Association called for more studies, and the European Food Safety Authority began assessing human health risks. Acting on this increased interest, ASTM International recently published Method D7574-09 – “Standard Test Method for Determination of Bisphenol A in Environmental Waters by Liquid Chromatography / Tandem Mass Spectrometry.” This method was developed and validated by the US Environmental Protection Agency using Environmental Solutions from Waters Corporation.
Providing fast, sensitive results, Waters breakthrough ACQUITY UPLC technology offers scientists a new tool in their search for answers about this important compound. Waters provides Environmental Analysis Kits, which include columns, vials, and sample preparation products, that are included in the published method.
As a world leader in separation science, Waters Corporation works with governments, research organisations and industrial partners worldwide to resolve new and emerging environmental concerns. Employing cutting-edge technologies and techniques, Waters has solutions for many of the challenges in the news today, including BPA, PFCs, and Pharmaceuticals and Personal Care Products. Whether you are engaged in the testing of air, water or soil, Waters has solutions for your environmental analysis. To learn more, please visit us at

New Environmentally Friendly GC-MS with Increased Sensitivity
Shimadzu (Germany) has launched a new GCMS-QP2010 Ultra gas chromatograph mass spectrometer (GC/MS) offering the highest performance in its class. It provides fast data measurement speed with five times higher sensitivity than previous models. In addition to improving laboratory productivity for high-speed analysis, it also offers improved applicability for comprehensive two-dimensional gas chromatography (GC×GC), which can achieve ultra high separation. It is also the first GC/MS system to have environmentally friendly features for saving power consumption and carrier gas.
A new technology in mass spectrometry has been developed increasing the scan speed of the GC-MS system. This patented technology, the Advanced Scanning Speed Protocol (ASSP), increases sensitivity at high scan speeds by over five times. This brings significant benefits to researchers processing metabolic compounds in food or biological samples for trace level analysis of unknown compounds by using fast GC method.
The combination of a high-speed GC method and high-speed “double jet cooling system” of the GC-2010 Plus dramatically reduces the analysis cycle. For example, in the case of VOC (volatile organic compounds), analysis time can be reduced by more than half from 37 minutes to 17 minutes.
The GCMS-QP2010 Ultra is capable of accepting simultaneous installation of two narrow- bore capillary columns into the MS. This allows users to switch applications without physically modifying the column installation. For example, regulated compounds such as pesticide and formaldehyde in drinking water need to be analysed separately using different columns. By connecting two different columns to the MS system, it is possible to perform both analyses in a single instrument without changing the columns.
The GCMS-QP2010 Ultra offers eco-friendly features reducing the power consumed in analysis standby mode by 36%. Use of Ecology mode over one year of operation can
reduce power consumption by 26%. Furthermore, annual CO2 emissions are cut by 30% and helium consumption being reduced by over 300 cylinders per year.
The new GCMS-QP2010 Ultra fulfills laboratory demands for enhanced productivity through various technologies which improve throughput, and helps to reduce operating costs while minimising environmental impact with its Ecology mode. With the introduction of this product, Shimadzu aims to increase its market share of gas chromatograph mass spectrometers worldwide.
