TraceDetect SafeGuard Displays Arsenic Content in 20 Minutes
Seattle, WA -- TraceDetect this week announced SafeGuard, an automated trace metals analyzer that simplifies the measurement of arsenic and other metals in water. The new analyzer will measure total arsenic down to 2 parts per billion (ppb), without requiring a chemist to operate the instrument and interpret results. SafeGuard has applications in community water systems, where government regulations demand stringent testing of arsenic in water.
SafeGuard is the first automated analyzer with the accuracy required to meet the 2006 EPA arsenic limit for drinking water. Water quality departments are accustomed to waiting two weeks for arsenic analyses from off- site laboratories. In addition to the prolonged health risks to customers, violators risk stiff fines for each day their arsenic levels exceed the limit. SafeGuard reduces those risks by displaying test results on site in 20 minutes.
"The TraceDetect SafeGuard is undeniably fast -- it produces the analysis on the spot," says Chet Auckley, Director of Quality & Regulatory Affairs for California Water Service Company (Cal Water). "We did our homework to make sure it would consistently give us test results that matched ICP-MS for accuracy. Nothing's more important, when it comes to arsenic compliance, than getting fast results that are very accurate. SafeGuard gives us exactly that."
A SafeGuard prototype was successfully tested at Cal Water by independent researchers from PureSense (Moffett Field, CA), who systematically compared SafeGuard's field test results against independent laboratory results. Based on the tests, PureSense recommended SafeGuard for arsenic compliance testing at Cal Water.
"The TraceDetect SafeGuard technology was found to be robust," said PureSense's Michelle Frey, PhD, Vice-President of Product & Service Delivery, who conducted the Cal Water field tests. "The system operated with very little human interaction. The results agreed with an independent commercial laboratory performing paired sample analyses using ICP-MS methods."
Studies have linked long-term exposure to arsenic in drinking water to cancer and other adverse health effects. In 2001, when the Environmental Protection Agency (EPA) adopted a new standard to reduce the public health risks from toxins in drinking water, it lowered the arsenic limit from 50 ppb to 10 ppb. The nation's 54,000 community water systems must be in compliance with the EPA rule by January 2006.
SafeGuard is a compact bench analyzer that uses Nano-Band technology to detect trace metals down to 2 ppb levels. SafeGuard performs speciation of arsenate and arsenite, for results that are more meaningful than a single reading of total arsenic. Automated sample preparation reduces setup and operating costs, compared to conventional ICP-MS methods.
