ICP-MS can detect elements at much lower concentrations (parts per trillion) compared to the parts per billion typically achievable with ICP-OES.
This sensitivity allows for more accurate measurements of trace elements even in very dilute samples.
The mass spectrometry approach used in ICP-MS is less prone to spectral interferences that can affect ICP-OES.
This is because ICP-MS measures the mass of ions, which can be distinguished more precisely than the wavelength of light measured in ICP-OES.
ICP-MS operates effectively across a broad range of concentrations, maintaining accuracy and precision even in samples with highly variable element concentrations.
The method used allows for a much higher degree of consistency even between different samples of the same batch.
