| Popis: |
Inductively coupled plasma mass spectrometry (ICP-MS) is a mass spectrometric method for detection of ions generated in an atmospheric plasma ion source. It provides multi-elemental detection of most elements of the periodic table combined with high sensitivity and large dynamic range. The method provides quantitative or isotopic information of elements in a sample. Two different types of instruments are found: Single-collector instruments are usually used in a scanning mode of the magnetic field for quantitative elemental analysis of a sample to measure one isotope after the other, whereas multicollector instruments are operated in a static mode of the magnetic field for precise isotope ratio analysis measuring all isotopes of interest simultaneously. In this chapter the “state of the art” of both types of instruments is discussed including fundamentals, special features, components, operation and the performance together with a description of the commercially available instrumentation and a discussion of selected applications. |
