Study Notes
ICP-MS Overview
- The main advantage of inductively coupled plasma-mass spectrometry (ICP-MS) is its ability to detect and quantify extremely low concentrations of elements in a sample.
Quadrupole ICP-MS
- The role of quadrupole ICP-MS is to separate and filter ions based on their mass-to-charge ratio, allowing for simultaneous detection of multiple elements.
Elemental Differentiation
- The key principle of elemental differentiation in ICP-MS is based on the difference in mass-to-charge ratio of ions, which enables the detection of specific elements.
Ionization
- Atoms must be ionized in the process of ICP-MS to create charged particles (ions) that can be detected and analyzed by the mass spectrometer.
ICP Conditions
- The inductively coupled plasma (ICP) used in ICP-MS operates at extremely high temperatures, typically exceeding 8,000°C, to ionize the sample atoms.
Learn about the applications of inductively coupled plasma-mass spectrometry (ICP-MS) in various fields such as environmental, medical, biological, industrial, and archaeological studies. Understand the use of quadrupole ICP-MS for determining element concentrations in different sample types.
