This study will focus on an ICP-MS sample preparation procedure and analytical methodology optimized for both toxic and nutritional elements in dried hops, a surrogate for the cannabis family of flowering plants. It will show that the wide dynamic range of the technique allows it to be used for the simultaneous determination of parts per billion (ppb) levels of heavy metals including Pb, As, Cd and Hg, together with high parts per million (ppm) levels of nutritional elements, such as P, Ca, K and Mg.
