The reason for this is that the platform temperature lags the tube wall temperature during the same ETV heating process. In view of the above facts, the compromise conditions of 2700 °C as vaporization temperature and 6 s as vaporization time were
chosen for platform vaporization fluorination assisted ETV–ICP-MS. Similar to literatures[14–17], a vaporization temperature of 2500 °C and vaporization time of 4 s were employed for wall vaporization fluorination assisted ETV–ICP-MS
