Environmental Laboratory Data Published for Demanding EPA 8270D GC Semivolatiles Analysis
Phenomenex Inc. (Germany), a global specialist in the research and manufacture of advanced technologies for the separation sciences, have announced the publication of a new technical note that provides information and tools for meeting and exceeding EPA Method 8270D guidelines. This method for semivolatiles (SVOCs) by GC/MS is widely used for solid waste testing in the environmental industry, and contains an exceptionally long list of compounds to be extracted from challenging, dirty matrices. GC column inertness is important for successful resolution of these target compounds. Phenomenex's Enviro-Inert Technology enables the production of columns that perform under the most demanding of conditions, even surpassing EPA requirements.
"Traditionally, general-purpose columns are not QC-tested to perform under the specific conditions that semivolatiles analyses present," explains Kristen Parnell, brand manager for GC products at Phenomenex. "Even columns marketed as 'inert' may not perform well for both the basic and acidic compounds found in these samples, because performance indicators specific to semivolatiles are not monitored in the QC process. A column may show good responses for bases at the expense of response for acids, or vise versa. GC chemists often must trim, condition or prime their columns and may still find that they fail to perform satisfactorily."
The application note details the importance of monitoring specific SVOC criteria during QC testing and reviews the performance of several GC columns typically used for EPA 8270D. A rigorous multi-test QC process, which includes requirements more stringent than the EPA method and ensures the high success rate of Zebron ZB-SemiVolatiles columns, is used as the basis for discussion and comparison.

26195pr@reply-direct.com High Performance Metals Analyser
Oxford Instruments’ (UK) new spark emission spectrometer FOUNDRY-MASTER Xline supports foundries and metal producers in determining metal samples fast and accurately while ensuring top performance at outstanding value.
Oxford Instruments has launched a new high performance, easy to handle and accurate spectrometer – the FOUNDRY- MASTER Xline designed specifically to meet the needs of the metals and steel markets. It is competitively priced and offers outstanding performance and practical features usually only found with premium class instruments.
The FOUNDRY-MASTER Xline is used for quantitative element analysis of metal samples and is designed as a benchtop unit. The high-resolution Multi-CCD optics is equipped with a vacuum chamber in order to cover the complete wavelength range from 165 nm to 780 nm, offering precise detection of all relevant elements in Fe and other matrices.
The unique Jet-Stream-Technology within the sample stand, which is open on three sides, offers the ability to measure almost any size or shape of sample, particularly large or irregular sample geometries. Additionally, the sample does not need to completely seal the spark stand opening. Tubes, bars and even wires can be analysed directly, using only one universal adapter. This major operational advantage strongly reduces the sample preparation time. The newly developed fully digital source (spark generator) is controlled via the external Windows PC and offers ideal excitation parameters. Argon consumption is reduced to a minimum, saving a considerable amount of operating expenses. The cleaning process is fast and instrument recovery efficient due to pre- aligned parts and quick connectors. The rugged and approved vacuum technology is essentially maintenance-free and has significantly lower operating costs than alternative inert gas purged systems.
The FOUNDRY-MASTER Xline is a reliable entry level laboratory spectrometer for the quantitative element analysis of metal samples. The new instrument is designed for stationary use as a benchtop unit.

25973pr@reply-direct.com Updates to ISO 14001
ISO 14001, Environmental management systems. Requirements with guidance for use, is the best known environmental standard. It has helped organisations worldwide understand and better control the environmental impacts of their activities, products and services. Since its original publication, the perception of sustainability has evolved with organisations becoming increasingly aware of the benefits of managing finite natural resources, responding and adapting to the challenge of climate change, etc. in a systematic and consistent manner. As such, the international standards community initiated the revision of ISO 14001 in 2011.
A committee draft was announced in April 2013. With the revision still in progress and the standard expected to publish in 2015, some of the key changes include: redrafting in line with the new "high level" structure being introduced across all international management system standards; strengthening the link between environmental management and top management's decision making; consideration of value chain and life cycle thinking; broadening the scope to include the environment's impact on the organization as well as the organisation's impact on the environment.
More updates, including a call for participation in the 2014 public consultation on the standard, to come.
The standard for laboratory tests to determine the heating and electrical performance of heat-led micro-cogeneration packages primarily intended for heating dwellings has now been revised. A micro-cogeneration unit (MCG) (also known as micro-combined heat and power unit) requires a substantially different test procedure from that for boilers, and the laboratory tests specified in PAS 67 have been designed to take account of these differences.

25984pr@reply-direct.com Multichannel Spectroscopy, for those Special Occasions
Avantes' (Netherlands) miniature spectrometers are well known for their high resolution in a small package. However, sometimes you want a combination of a broad range with a high resolution and that's where the Avantes Multichannel spectrometers come in handy. Up to 10 spectrometers combined into one housing with the possibility to combine all those into a single output spectrum, use them as master/slave or let them be triggered separately.
With over 15 years of experience in multichannel spectroscopy, Avantes offers one of the widest variety of choice in the market today. In a standard 19" rack mount, up to 10 spectrometers can be combined. These can be any from the Avantes catalogue, starting with the robust and versatile UV/visible AvaSpec-
ULS2048 up to the TEC cooled AvaSpec-NIR2.5 near infrared spectrometer. The total number of spectrometers connected to a single computer is only limited by USB, memory or processor limitations of the host computer.
Benno Oderkerk, founder and CEO of Avantes: "Many of our customers want to use several spectrometers at the same time, for instance to obtain a higher resolution with a broad range. We also equip multichannel spectrometer systems with trigger options, one spectrometer triggering another or them being triggered by an external event. Other options are a master/slave configuration, or all the options I've mentioned combined into one system. The possibilities are endless."
The Avantes multichannel spectrometers are frequently used for plasma measurements and LIBS configurations. In general, applications where high resolution with a broad range is needed in combination with a synchronised measurement. In AvaSoft, all spectrometer channels can be combined into one graph, making one virtual spectrometer.
