ICP-OES; Systems Used by Textile Industry to Ensure Leading Brands of Jeans Free from Contaminants
PerkinElmer (UK) is helping the textile industry regulate the use of prohibited allergenic and toxic substances in garments with its high performance Optima ICP-OES systems. Swedish analytical company, Swerea IVF, is using the versatile and precision-engineered Optima ICP-OES 2100 to analyse exposure to residual metals from leading brands of jeans. The speed and accuracy of the Optima system is proving invaluable in the detection of low levels of heavy
metals, including mercury and lead, which can have poor sample stability.
The analysis is performed as part of the OEKO-TEX certification for the safety of textiles. Swerea IVF employs an analytical model to mimic how metals are partly dissolved and transferred to the skin while wearing textile garments, such as jeans. Once the metals have been extracted from the material using an artificial sweat solution, the samples are analysed immediately using the Optima ICP-OES to reduce the risk of decomposition. The multi-component spectral fitting (MSF) algorithm in the ICP software, combined with excellent wavelength stability, ensures optimum detection results are achieved. Anders Blom, Swerea IVF, Sweden, comments, "We are very pleased with the Optima system from PerkinElmer. It is so simple and easy to run the analysis on undiluted samples and the detection limits are excellent. We compared the Optima with several other ICP-OES instruments, but were impressed by the sequential scanning on PerkinElmer's Optima 2100 system and consider it to be a high-resolution ICP-OES instrument."
"We are delighted to be working with Swerea IVF to help ensure the safety of consumers of popular brands of clothing," said Dusty Tenney, president, Analytical Sciences and Laboratory Services, PerkinElmer, Inc. "Consumer product safety is a key objective for PerkinElmer. We are committed to discovering new and more effective ways of using our detection capabilities to keep consumers safe from toxins and contaminants in everyday products."

New Transportable GC/MS for High- Performance, Out-of-Laboratory Analysis
Agilent Technologies (Asia) introduce the 5975T Low Thermal Mass (LTM) Gas Chromatography/Mass Spectrometry Detector (GC/MSD), the industry’s first commercial transportable GC/MS system that delivers laboratory-quality analysis. Using proprietary LTM technology, Agilent has developed the 5975T LTM GC/MS to be smaller, more rugged and to consume less power than in-lab GC/MS instruments, yet capable of the same high-quality performance in the field.
Agilent’s LTM technology eliminates the conventional GC oven by wrapping the GC column(s) with a heating element and temperature
sensor. This provides rapid heating and cooling of the column for higher throughput. It also reduces power consumption by 46 percent, shrinks the footprint by 38 percent and reduces weight by 35 percent. "Agilent’s LTM technology will continue to enable faster and smarter GC and GC/MS systems in the future," said Jeff Li, Agilent general manager of Emerging Market Measurement Solutions, Chemical Analysis Group. "The 5975T LTM GC/MSD is an example of how to deliver laboratory-quality results in a compact, green package."
The 5975T LTM GC/MSD is particularly well-suited for chemical warfare analysis, first responders, and military and homeland security officials who need fast and highly accurate results in the field. Additional out-of-laboratory applications include food safety testing and environmental monitoring.
The 5975T LTM GC/MSD has several key features that enhance customer ease-of-use. The LTM technology allows customers to quickly change the LTM column module in the field, aiding in service and maintenance. The inert ion source allows for the highest performance with samples containing active compounds. A liquid auto-injector option is available, enabling calibration verification and semi-volatile organic compound analysis in the field. Additionally, with the classical electron impact (EI) spectra, quadrupole technology delivers National Institute of Standards and Technology (NIST) searchable spectra of unknowns. With a 1.8u to 1050u mass range, the 5975T LTM GC/MSD offers a wide range of applications.

The new Eco-Box* service from ELGA Process Water (UK)is a recycling and disposal service for all laboratory water system consumables and small hazardous waste. Eco-Box* complies with the latest legislation for disposal of hazardous waste, and helps laboratories to reduce their impact on the environment by minimising the volume of waste that is sent to landfill. Eco-Box* is a secure, durable plastic storage container for laboratory water system consumables and small quantities of hazardous waste. Once filled, the Eco-Box* is collected and the contents recycled or reused wherever possible. ELGA Process Water will complete all the necessary paperwork to satisfy duty of care and safety legislative requirements.
The Eco-Box* service can be tailored to individual needs, with collections undertaken nationwide on a scheduled or call-off basis. Using the Eco-Box*, all workplaces can benefit from a quick, safe and simple way to protect the environment and comply with the latest waste legislation.

Analytica 2010 closed its gates in Munich, Germany with nearly 33,000 visitors from 120 countries. An audience of highly qualified visitors and an increase in the number of exhibitors to 1,038 companies from 37 countries created an atmosphere of optimism in the industry. Visitors gave the fair top marks: They confirmed analytica as the industry’s leading trade fair and praised it for the presence of all key players. The scientific analytica Conference held in conjunction with the fair and the extensive program of related events saw an increase in attendance, and the audience of international professionals was convinced by both their content and their quality.

GrayWolf (USA) introduces a fully revised version of its environmental instrumentation operating software, redesigned from the ground up. WolfSense®
WolfSense 2010 also operates on GrayWolf’s new embedded computer instruments, such as the WolfPack® , SO2 , %RH, Temperature and much more.
2010, in conjunction with GrayWolf sensors, transforms Windows XP/VISTA/7 notebook PCs and Windows Mobile Pocket PCs into sophisticated air quality measurement instruments. A greatly improved user interface makes operation of this advanced instrumentation far easier-to-use than much more basic units; and a number of new features have been added.
Modular Area Monitor. Available
parameters include Volatile Organic Compounds (VOCs), Carbon Dioxide, Particulates, Differential Pressure, Air Velocity, Ozone, Ammonia, Hydrogen Sulfide, CO, NO, NO2
Once measurements have been trend-logged over time or spot-logged; review, analyse and report on the data and field-collected notes with the included WolfSense PC software. Optional Advanced Report Generator software automates the entire reporting process.
