Written by What is ICP-MS
It is an elemental analysis technology that enables the identification and measurement of most of the periodic table elements in various sample types. It atomizes the sample and creates atomic and small polyatomic metal ions, which are then detected. It is suited to the rapid multi-element analysis of aqueous solutions, emulsions, and biological fluids.
What are its Benefits
ICP-MS combines the sensitivity, ease of use, and flexibility needed to manage multiple tasks. Additionally, it's reliably fast with accurate performance and low running costs. Researchers can determine which elements are present in a wide range of samples through this technology, including human tissue, soil, rocks, and animals.
What Types of Samples can This Testing Analyze?
Coupled with plasma mass spectrometry, ICP-MS is used to detect very low levels of trace elements in solids, liquids, and gasses. However, solid samples must be converted to fluids first before testing.
It offers extremely high sensitivity to a wide range of elements. The bulk chemical analysis technique can simultaneously determine up to 70 elements in single sample analysis. The elements include but are not limited to; Calcium, Cerium, and Copper. The test also provides multi-elemental analysis without interference.
How is the Sample of ICP-MS Prepared?
It works by introducing the sample into a high-temperature plasma (8000 °C) which vaporizes and atomizes the sample. The detector then records the number of ions arriving at it as a function of their mass/charge (m/z) ratio.
What Cannot be Analyzed by ICP-MS Testing?
You cannot use it to evaluate most gaseous elements and elements that do not have naturally occurring isotopes, such as actinides.
What are Its Limitations?
It can cause many interferences in biological and environmental samples analysis. When used for elemental analysis, it requires an expensive instrument. Therefore, the technology is largely limited to a few laboratories, either academia or industries.
