Inductively coupled plasma mass spectrometry

Inductively coupled plasma mass spectrometry (ICP-MS) is an advanced analytical technique, which combines inductively coupled plasma and mass spectrometry, and can be used to quickly and accurately determine the composition and content of elements in samples.

Firstly, ICP-MS uses high-frequency inductively coupled plasma to generate high-temperature and high-energy plasma gas, and converts the sample into ionic state. Then these ions are analyzed by mass spectrometer, and separated, detected and quantified according to the mass-to-charge ratio of ions.

ICP-MS has the following main features and advantages:

High sensitivity: ICP-MS can measure most elements, and has extremely high sensitivity for the analysis of trace or ultra-trace elements, usually reaching ppt (that is, the concentration of one trillion) or lower.

Wide linear range: ICP-MS has a wide linear dynamic range in element determination, which can meet the analysis requirements of different concentration levels.

Multi-element analysis: ICP-MS can determine multiple elements at the same time, which improves the analysis efficiency and sample utilization.

High precision and accuracy: ICP-MS has high precision and accuracy, and can be used for various quantitative analysis.

Fast analysis speed: ICP-MS can complete the rapid analysis of multi-elements in a short time, which is suitable for batch analysis of large samples.

ICP-MS is widely used in environmental monitoring, geological science, metallurgical industry, biomedicine, food safety and other fields. It can be used to detect pollutants in water, soil and air, metal elements in ores and rocks, trace elements in drugs and biological samples, etc.
