Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is an analytical technique used to detect and quantify trace elements in various samples. It works by ionizing the sample using an inductively coupled plasma, which generates ions that are then analyzed by a mass spectrometer. This method is highly sensitive and can measure concentrations down to parts per trillion. ICP-MS is widely used in fields such as environmental monitoring, geology, and food safety. It allows scientists to analyze metals and non-metals in complex matrices, making it valuable for assessing contamination levels and ensuring compliance with safety regulations.
