WebWhat is TIMS? Thermal ionization mass spectrometry (TIMS) is designed to obtain high precision isotopic information. Ions are created by passing a current through a thin metal … The filaments used are made from tantalum (Ta), tungsten (W), platinum (Pt) or rhenium (Re). Conventionally, there are two filaments used in TIMS. One filament is for the sample and is called the sample filament. The liquid sample is placed on the sample filament which is then evaporated to create ions. … See more Thermal ionization mass spectrometry (TIMS) is also known as surface ionization and is a highly sensitive isotope mass spectrometry characterization technique. The isotopic ratios of radionuclides are used to get an … See more When the hot filament heats the liquid sample, the fermi levels within the sample reaches parity with that of the metal. In turn, this allows for an electron to tunnel from the sample to … See more The relative abundances of different isotopes are then used to describe the chemical fractionation of different isotopes, travel in different reservoirs of non-radiogenic isotopes, and age or origins of solar system objects by the presence of … See more
