| Summary: | In connection with the age determination of geologic samples, an attempt was made to improve the tetramethyl lead method which is commonly used for the isotopic analysis of lead. A micro-scale appliance was devised to prepare tetramethyl lead from lead iodide in small quantities. Anisole was used as a solvent for the Grignard, s reaction with the intention of increasing partial pressure of tetramethyl lead in a gas mixture on which the isotopic analysis of lead was carried out. This led the authers to perform the isotopic analysis of lead in suchasmall quantity as 200 μg with a mass spectrometer, CEC21-103A. Detailed discussions are made on the whole experimental procedure as well as the analysis of mass spectra. |
