ICP-MS (inductively coupled plasma mass spectrometry) is a high-sensitivity analytical technique used to measure the concentration of metal and non-metal elements in liquid samples. It induces coupled plasma in a high-frequency electromagnetic field, and the sample is ionized. A mass spectrometer is used to quantify the mass of the elemental ions to determine the concentration of each element in the sample. ICP-MS is characterized by high accuracy and precision, simple sample preparation and injection
