Analysis of Thallium in gold plating solution (Flame method)
Because of its excellent corrosion resistance, conductivity and other properties, gold plating is frequently used in electronics and mobile phone, as well as in jewelry, etc. Thallium (TI) is sometimes added to gold plating solution as a crystal regulator to obtain stable precipitates in the solution for bonding use. Stable quality can be maintained by controlling the TI concentration in the plating solution. ZA3000 which features the polarized Zeeman background correction method, can make precise quantitative determinations that correct for background without being affected by materials coexisting in the plating solution.
