Thermal Ionization Mass Spectrometry (TIMS) is an analytical technique used to determine the isotopic composition of elements, particularly useful for radiometric dating and tracing geological processes. This method utilizes thermal ionization to convert sample atoms into ions, which are then separated and detected based on their mass-to-charge ratio. TIMS is particularly significant in isotope geochemistry as it provides high precision and accuracy in measuring isotopes like Lutetium (Lu) and Hafnium (Hf) in the Lu-Hf dating system.
congrats on reading the definition of TIMS. now let's actually learn it.
