    Product Description

    Heavy Metals Mixture 5 (CRM) (Item No. 41850) is a certified reference material mixture containing heavy metals, which have been found as environmental contaminants in water, soil, plants, and Cannabis products.1,2,3,4,5,6,7 The mixture contains arsenic (As), cadmium (Cd), lead (Pb), mercury (Hg), and chromium (Cr). Levels of these heavy metals are frequently monitored in Cannabis samples and have been monitored in C. sativa plants used in phytoremediation of cadmium-polluted soils.8,9,10,11,12 The mixture is supplied in a plastic bottle with a 30 ml fill volume. It is designed for use in atomic absorption, inductively coupled plasma (ICP), and ICP-MS applications for the detection and quantification of these heavy metals in environmental monitoring and action limit testing. This product is intended for research and environmental testing applications.

    WARNING This product is not for human or veterinary use.
