Improvements in experimental techniques of conventional K/Ar and Ar/Ar geochronological methods
The performance of a noble gas mass spectrometer used for K/Ar–Ar/Ar dating has been improved in three ways. The background has been decreased by surrounding the ion source with a cylinder of St707 NEG strip. A simple method has been found for rotating the sample during irradiation in the nuclear re...

| Summary: | The performance of a noble gas mass spectrometer used for K/Ar–Ar/Ar dating has been improved in three ways. The background has been decreased by surrounding the ion source with a cylinder of St707 NEG strip. A simple method has been found for rotating the sample during irradiation in the nuclear reactor. Finally, a furnace that does not require the use of an additional vacuum system has been constructed for degassing the irradiated samples. © 1998 John Wiley & Sons, Ltd. |
