Abstract:
... Ultrafast measurement using dwell times below 100 μs down to 10 μs is a relatively new feature of single particle analysis using ICP-MS. In this study, we tested the effect of shorter dwell times on the particle size detection limit (Dd.ₗ.). Decreasing dwell times below 100 μs did not lead to a statistically significant decrease in Dd.ₗ. The particle size detection limit (quadrupole ICP-MS) of sil ...
