High Temperature NMR experimental setup
High temperature setup associating CO2 laser heating and crucible or levitation device.
Three of our spectrometers (750MHz, 400MHz and 300MHz) are equiped for laser heated High or Very High Temperature experiments :
-
Closed BN crucible container (Tmax ~1200°C) - application
for molten silicates or molten salts
-
Aerodynamic levitation device (Tmax ~2500°C) for direct laser heating of the sample droplet under oxidizing or neutral atmosphere - application to refractory liquids (aluminates, alumino silicates...)
-
Two CO2 lasers of typically 100 to 150W depending on the system for heating from top / bottom with computer control
