ICP-MS (Inductively Coupled Plasma Mass Spectrometry)

This is a powerful analytical technique that combines the high-temperature ionization characteristics of inductively coupled plasma with the sensitive detection capabilities of a mass spectrometer.
It has extremely high sensitivity and can detect extremely low concentrations of elements, with detection limits usually reaching ppt (ng/L) or even lower levels. At the same time, it can simultaneously determine multiple elements, including most metal elements and some non-metal elements.
ICP-MS plays an important role in many fields:
Environmental monitoring: such as detecting trace heavy metal pollution in water, soil and atmosphere. For example, accurately determine the content of harmful elements such as lead, mercury, and cadmium in water to assess environmental quality and pollution levels.
Biomedicine: used to analyze trace elements in biological samples, such as metal element content in blood and urine, which helps disease diagnosis and drug research.
Food safety: Detect heavy metal residues in food to protect public health. For example, detect the arsenic content in rice to ensure that it meets safety standards.
Geological exploration: Analyze the trace element composition in rocks and ores to provide important data for geological research and mineral exploration.
However, ICP-MS also has some limitations, such as expensive instruments and equipment, high maintenance costs, and strict sample pretreatment requirements. However, ICP-MS is still an indispensable analytical method in analytical tasks that require high precision and simultaneous detection of multiple elements.
