The basic tool for the analysis of metal and metal materials, rock and mineral analysis device spectrometer is able to separate and detect the ions (charged particles) of different materials. The mass spectrometer generally has four basic parts, an ion source, accelerator mass filter and a detector. The most commonly used mass spectrometer with thermal ionization (TIMS) and the magnetic mass filter and its modifications for the analysis of negatively charged ions (N-TIMS). Other types of mass spectrometry mass spectrometry of the secondary ions (ie. Ion probe used for elemental and isotopic analysis, SIMS), mass spectrometry, gas source (ie. Mass spectrometry of light elements, e.g. C, O, N, H, S, Ar ; GSMS) and mass spectrometry with inductively coupled plasma (mainly used for elemental analysis, ICP-MS). Analysis of isotopic composition classical TIMS usually requires prior chemical separation of analyzed elements to avoid isobaric interference between equally heavy isotopes of different elements or molecules. Own age for most isotopic dating methods, eg. Rb - Sr, Sm -nd, Lu - Hf, derived from the slope of the regression line interspersed with the isotopic composition of elements of several subsidiaries kogenetických samples (rock or minerals) with different ratios of parent and daughter elements. While the isotopic composition of elements subsidiaries can directly measure the mass spectrometer, the concentration of parent and daughter elements are usually determined by isotope dilution.
