Alkaline aqueous sodium bicarbonate buffers (pH 9.4-9.8) are the most commonly used solvents for zinc determination using this product. Sodium citrate may be included in the formulation to mask the presence of iron, and detergents such as Triton X-100 can be added to improve stability. For details on exact concentrations, consulting peer-reviewed literature and commercial kit protocols is recommended.
