Portable Heavy Metal Analyzer

Product Model: NanoTek 2000

As the world’s first most compact and lightweight portable heavy metal detector, it delivers high detection sensitivity with a minimum detection limit down to 1 ppb. A single sample test takes less than 5 minutes, enabling rapid qualitative and quantitative analysis of water quality from unknown pollution sources. It features high detection accuracy; its test results are comparable to those of AAS and ICP, with a measurement error below 10%.

Product Overview

Heavy metal pollution in water resources has increasingly become a severe global concern. The World Health Organization has stipulated ppb-level safety reference limits for heavy metals in water across various fields. The Chinese government has also issued a series of environmental safety standards, such as GB 5749—2006 Sanitary Standard for Drinking Water and CJ/T 206—2005 Water Quality Standard for Urban Water Supply, which require heavy metal content in safe drinking water to be controlled at the ppb level.

Conventional optical detection methods suffer from high operating costs and low sensitivity at the ppm level. Atomic absorption spectrometry requires costly equipment and complicated sample pretreatment, making it unsuitable for on-site and emergency monitoring scenarios.

NanoTek 2000 is a patented product jointly launched by Shenzhen Lonstone Scientific Instrument Co., Ltd., Nanjing University and the Chinese Academy of Sciences. Adopting an innovative design concept in electrochemical analysis and a uniquely designed reaction cell, the instrument greatly improves detection accuracy and sensitivity, while simplifying operation.
