3 principle
The use of a particular concentration of hydrochloric acid, the toy material in the specific conditions of chromium, tin migration elements, the resulting sample solution was added after the internal standard
After using ICP-MS for testing. According to the quantitative relationship between the mass-to-charge-mass ratio and its concentration, the migration of chromium and tin
Shift amount. According to the total migration of chromium and tin elements, screening of hexavalent chromium in toy materials and organotins.
