PF7 Heavy Metal Analyzer

The heavy metal analyzer PF7 features good accuracy, high sensitivity, simple structure, small volume and easy operation.

The automated PF7 is an ideal supplementary of ICP-MS if testing dozens of elements in ULTRA trace elements. A perfect replacement of ICP-MS if only testing heavy metals like Arsenic, Mercury, Cadmium and Lead.

Popular instruments in various market and research industries including: Cannabis, Environment (Water and Soil), Agricultural, Public health, Pharmaceutical, Metallurgical, Food and beverage, Clinical, Geological, Petrochemical, and more.

Also it comes with XYZ axis auto sampler AS4 as an optional accessory making the analysis even simpler
