Times Cited Count：2 Percentile：14.88(Chemistry, Multidisciplinary)Online solid-phase extraction-inductively coupled plasma-quadrupole mass spectrometry with oxygen dynamic reaction cell (online SPE-ICP-MS-DRC) was shown to be a thorough automatic analytical system, circumventing the need for human handling. At three stepwise separations (SPE-DRC-Q mass filters), we showed that interference materials allowed the coexistence of abundance ratios of 1.5

Technetium-99 (Tc) is a pure beta-emitting radionuclide with a long half-life (210 000 years), produced with a yield of about 6% during the fission of 
U and 
Pu. The properties of high mobility in environment and concentrated into specific seaweeds were applied as a tracer for radioisotopes released into the environment. Inductively coupled plasma-mass spectrometry (ICP-MS) is the main method for Tc analysis; however, the isobars (Ru and 
MoH) interfere the quantification. In this study, a multi-stage separation and analysis system (online SPE-ICP-MS) for Tc was constructed by attaching a solid phase extraction (SPE) resin to a flow injection (FI) system and combining it with a collision reaction cell (CRC) in an ICP-MS. In addition, a high sensitivity for detecting trace amounts of Tc was developed.
