1IntroductionOverviewThe CETAC QuickTrace M-7600 mercury analyzer measures trace levels ofmercury in aqueous solution by Cold Vapor Atomic Absorption Spectrometry(CVAAS). CVAAS does not require heating the sample with a flame, plasma, orfurnace. The mercury analyzer’s modular design permits remarkably easymaintenance access and a reduced countertop footprint. Sturdy construction,drift-stabilized double beam optics,

The primary audience for this manual consists of mercury detection and mercury measurement laboratory managers, chemists, technicians, field - service engineers and owners of the QuickTrace M-7600 mercury analyzer. To use this product effectively, you should have a basic knowledge of mercury

Studies also show that elevated methyl-mercury levels observed in reservoir fi sh eventually decline to background concentrations after about 20 to 35 years. Why Is Mercury In Fish A Problem?

50% mercury are widely used throughout the United States. An estimated 35 tons per year of mercury are released to the environment through use of amalgam fillings. In California, historic mercury mining in the Coast Ranges and mercury used for gold ore recovery in the Sierra Nevada are also a continuing source of mercury. History of Occurrence
