Working principle and application fields of inductively coupled plasma mass spectrometry
Date: 2025-04-18Read: 2
ICP-MS (Inductively Coupled Plasma Mass Spectrometry)It is a highly sensitive and multi-element simultaneous analysis trace element detection technology widely used in fields such as environmental science, geology, materials science, life science, and medicine.
working principle
-
Inductively Coupled Plasma (ICP)High temperature plasma (temperature up to 6000-10000 K) is generated through high-frequency induction coils to completely dissociate and ionize elements in the sample into single charge ions.
-
Mass spectrometry analysis (MS)Ions are separated by mass analyzers (such as quadrupole, time-of-flight mass spectrometry, etc.) according to the mass to charge ratio (m/z), and the detector records the ion signal intensity to achieve qualitative and quantitative analysis.
Application field
-
Environmental ScienceMonitor heavy metal pollution (such as lead, mercury, cadmium) in water bodies, soil, and atmosphere.
-
geologyTrace element and isotope analysis in rocks, minerals, and geochemical samples.
-
Materials ScienceImpurity element detection in semiconductor materials, nanomaterials, and alloys.
-
Life Sciences and MedicineAnalysis of trace elements in biological samples (blood, tissue) and research on disease diagnostic biomarkers.
-
Food ScienceDetection of nutritional elements (such as iron and zinc) and harmful elements (such as arsenic and lead) in food.
