Sample heating and analysis |
| abstract |
An apparatus (1) for heating a sample (2) under vacuum conditions, especially for extracting gas (105) from the sample for isotope ratio studies, the apparatus comprises: a first vacuum enclosure (18) for containing the sample disposed within a crucible (4); and a resistively heated electric heating element (26), disposed outside of the first vacuum enclosure and positioned around at least part of the crucible, the heating element being disposed within a second vacuum enclosure (20) and comprising a graphite carbon resistor (25). Preferably the heating element has cooled input and output terminals at least partly electroformed onto the resistor, and a gas purification system (6) and a mass spectrometer (8) are provided for isotope analysis of the gas and sample. <IMAGE> |
