Applications of magnetic sector ICP-MS in geochemistry

Inductively coupled plasma mass spectrometry (ICP-MS) is a technique that provides rapid and sensitive multielement and isotope analysis of various environmental materials. This technique has developed into a valuable tool for data acquisition in geochemistry. Quadrupole and magnetic sector mass analysers are the most important types of mass filters that are commercially available with these instruments. Magnetic sector instruments are more expensive than quadrupole-based instruments, but provide enhanced sensitivity and higher mass resolution. This paper reviews applications of single-and multiple-collector magnetic sector ICP-MS in different fields of geochemistry and shows where the use of magnetic sector ICP-MS is advantageous.
