Questions and Answers

Explain the principle of elemental differentiation in inductively coupled plasma-mass spectrometry (ICP-MS).

ICP-MS differentiates elements based on their atomic mass by ionizing atoms to form positively charged particles and then analyzing their atomic mass using mass spectrometry.

How is inductively coupled plasma (ICP) used in the ionization step of ICP-MS?

ICP is used to create a highly ionized phase at a very high temperature, which ionizes the atoms to form positively charged particles for analysis.

What are the strengths and limitations of inductively coupled plasma-mass spectrometry (ICP-MS)?

The strengths of ICP-MS include low detection limits and multi-element capability, while the limitations involve the need for users to be aware of the technique's strengths and limitations, and its reliance on the isotopic composition of elements.

What is the significance of quadrupole ICP-MS in determining element concentrations in various sample types?

<p>Quadrupole ICP-MS is significant in determining element concentrations in diverse sample types due to its low detection limits and multi-element capability.</p> Signup and view all the answers
