Automated Helium Thermochronology Uranium-helium thermochronometry is a sensitive and cost-effective method of radiometric age dating. This can be used to determine the thermal history of the Earth’s crust, with widespread application in both research and economic geology. This technology is of major benefit to the petroleum and mineral resources industries. Users can quantitatively determine the low temperature thermal histories of mineral belts and petroleum basins. This data is fundamental in the exploration for deposits of minerals, oil and gas. Features
- A Turnkey system Integrating a 980nm diode laser and an automated X-Y stage for the automated extraction and measurement of radiogenic helium from mineral samples.
- Fully automated with a load capacity of up to 25 individual samples – each sample is heated for a user-specified time and the extracted gases are then purified, spiked with 3He, and analysed 4He abundance
- using a quadrupole mass spectrometer.
- Fully automation via user-friendly LabView software that integrates the mass spectrometer, laser diode power supply, X-Y motion controller, video camera and valve sequencing.
