VG PRISM

machine specifications:

• Dual inlet, triple collector IRMS (Isotope Ratio Mass Spectrometer) devoted for ¹³C/¹²C and ¹⁸O/¹⁶O ratio analysis using CO₂ as a measuring gas.
• High precision δ¹⁸O and δ¹³C analysis of silicates and carbonates with precision better than 0.02 ‰. Refer to preparation systems.
• Sample size is normally 100 µl CO₂, but 1 µl CO₂ is possible with cold finger.
• A cracker manifold is attached for autorun of 10 samples.
• Automated δ¹⁸O measurement of water samples (24 samples a day) with precision better than 0.05 ‰.

applications:

• Role of water and CO₂ in the study of magmatic hydrothermal systems.
• Water circulation in the Earth's surface
