Voltammetric Device Measures Labile Copper Content The Metrohm 797 VA Computrace can be used for the determination of labile copper in sea water. Spectroscopic methods can only determine the total concentrations of metals, but with voltammetry it is possible to differentiate between the different oxidation states of copper. This allows statements to be made about the biological availability and toxicity, making voltammetry an essential tool in environmental analysis. Copper is one of the most toxic-heavy metals known to marine life, generally concentrations of heavy metals are comparatively low in open sea areas where human activities have not yet had a major detrimental effect. However, in coastal area, contamination is usually more widespread often in offshore sediments close to municipal and industrial discharge points. Many marine and research institutions are interested in determining the relationship between the labile (or free copper) and total copper, both of which can easi...

Tyco Offers Sigma-Link Copper-Cabling Solutions Sigma-Link from Tyco Electronics's Amp Netconnect business unit is a range of pre-terminated high-speed copper-cabling solutions designed for ease of installation in office networks and data centres. The Amp Netconnect Sigma-Link system offers all performance and link classes including Category 6/Class E, Category 6A/Class EA and Category 7A/Class FA to support current applications at speeds of up to 10Gbit/s over copper cable. The Class FA version has been developed to support future applications at up to 40Gbit/s. The system is fully standards compliant and is suitable for equipment cabling in data centres. Performance of the Sigma-Link system is ensured by factory testing of all cable assemblies. Traceability of the far end is achieved by an integrated plastic optical fibre, which facilitates identification after installation. The system is fully compliant to TIA/EIA 942 and EN 50173-5, which are specific data-centre standards....
