October 2006, Sunnyvale, CA—Dionex Corporation announces the addition of a platinum electrode to its popular line of disposable working electrodes. Electrochemical detection has never been easier or more reliable, featuring quick start-ups with no more polishing required. For consistent results between users and over time, disposable electrodes are the proven advantage. The unique properties of platinum, combined with newly developed integrated amperometry detector waveforms, make it possible to achieve direct detection of a number of compounds previously detected only with postcolumn LC or LC-MS. Alcohols, aldehydes, alkenes, alkynes, carboxylic acids, chelating agents, ethers, ketones, nitriles, phenols, sulfoxides, thioethers, azide, cyanide, sulfide, and sulfite are some of the analytes detected using platinum with integrated pulsed amperometric detection (IPAD); with sub-ppm detection limits for many of these molecules. IPAD is more effective than DC amperometry because it overcomes electrode fouling and short-term response degradation. Like the gold and silver disposable electrodes offered by Dionex, the new platinum electrodes provide reproducible analysis, electrode to electrode and lot to lot, while maintaining peak efficiency and excellent sensitivity. Each lot is tested for key application performance, ensuring reproducibility, and each is serialized for tracking purposes. Dionex (NASDAQ:DNEX) is a global leader in the manufacturing and marketing of liquid chromatography and extraction systems, consumables, and software for chemical analysis. The Company's systems are used worldwide in environmental analysis and by the life sciences, chemical,petrochemical, food and beverage, power generation, and electronics industries. Our expertise in applications and instrumentation helps analytical scientists to evaluate and develop pharmaceuticals, establish environmental regulations, and produce better industrial products.
