The Aquacounter HG-400 low-cost mercury analyzer (photo) requires small sample sizes and minimal reagents, so it generates a small volume of waste in sampling. Its detection limit is 0.5 ppt at sample volumes of 5 mL, and 5 ppt at sample volumes of 20, 100 and 250 mL. The mercury detector can be used to analyze trace mercury levels in effluent treatment application, and can also be used to detect trace mercury in food, ambient water, or as an impurity in copper and other metals. — JM Science Inc., Grand Island, N.Y.
