【求助】icp-ms测汞

The determination of Hg using ICP-MS is very tricky from a sample preparation perspective as well as the measurement perspective. Losses are often found due to both volatilization as well as adsorption to the container walls. Standard preparations of Hg in dilute nitric acid using plastic containers are not stable long enough to obtain reliable data and the washout times are long. If your FIMS approach is working, I do not suggest that you switch.
