When you need to be sure, make it Ultra Pure.

While the USP, EP and FCC have established limits for vagrant metals, Jost customers have applications requiring higher purity mineral salts. We manufacture a line of Ultra Pure salts with impurity levels much lower than the USP/EP/FCC monographs. With a maximum of 1 ppm for Pb, As, and Cd, and a maximum of 0.1 ppm for Hg, Ultra Pure products also meet European Regulation 231/2012 and the expected ICH and USP elemental impurity guidelines.
