A new ICP-TOFMS. Measurement and readout of mass spectra with 30 micros time resolution, applied to in-torch LA-ICP-MS.
In-torch LA-ICP-MS was implemented into an in-house-built ICP-TOFMS system. The fast data acquisition capabilities of the new configuration allowed simultaneous multi-element measurement and readout of in-torch LA-ICP-MS signals with 30 micros time resolution. The measurements confirmed previously observed fine structures of in-torch generated signals and provided new insights in the dynamic processes in the plasma on a microsecond time scale. The new setup is described in detail and first figures of merit are given.
