Inductively coupled plasma mass spectrometry (ICP-MS) is an elemental analysis technology capable of detecting most of the periodic table of elements at milligram to nanogram levels per liter. It is used in a variety of industries including, but not limited to, environmental monitoring, geochemical analysis, metallurgy, pharmaceutical analysis, and clinical research.
The Inductively Coupled Plasma (ICP) is an ionization source that fully decomposes a sample into its constituent elements and transforms those elements into ions. It is typically composed of argon gas, and energy is "coupled" to it using an induction coil to form the plasma.
ICP-MS systems are powerful analytical instruments; to obtain the best quality of data from these instruments, sample preparation and introduction methods must be performed with care. Also, data acquisition and processing should be thoroughly scrutinized.
In this section, you will:
Learn how different sample types are prepared for analysis, and how instrument drift and background are accounted for during ICP-MS.
Raw ICP-MS data are often calibrated to account for interferences and instrument drift. Understand which techniques, including spiking and standard additions, are used to calibrate data when plotting sample concentration curves.
Find out which ICP-MS system is ideal for your lab by understanding how mass analyzers and magnetic sectors differ, how sample interference is filtered out, and how single ions are detected following selection.
We understand the challenges you face when analyzing complex sample matrices, which inspired us to redefine triple quadrupole technology with unique ease of use. Find out how the Thermo Scientific iCAP TQ ICP-MS, which includes triple quadrupole technology, significantly improves interference removal.
