Webb6 apr. 2024 · Specifically, THz waves far from the center traveled longer before focusing to the PCA detector, and are, therefore, observed at longer time delays in the THz-TDS spectra. The presence of the broad dip at ∼27.5 ps also suggests that the THz waveform may be chirped. Note that the THz emitted from the PCA contains high- and low … WebbOver the last years, inductively coupled plasma mass spectrometry (ICP-MS) has been applied as a method for human-biomonitoring of metals in the concentration range of occupational and environmental medicine. In large scale routine monitoring, the determination of mercury (Hg) by ICP-MS remains challenging due to s
