In-situ analysis of Hafnium isotopic composition

Test category: In-situ analysis of Hafnium isotopic composition
Test target: zircon, baddeleyite, etc.
Test period: 20-30 work days
Requirements:
1.thin sections, thick sections, or polished sections, length ≤ 5 cm, width ≤ 3 cm, thickness ≤ 0.8 cm, analysis spot marked on the reflected light images.
2. measurements can be done either by customer or by our technician.
3.Zircon epoxy disc is needed. zircon
176Yb/177Hf should be < 0.15. Please inform us in advance if not.
Analytical methods:
In situ Hf isotope ratio analysis of zircon by LA-MC-ICP-MS
Data quality:
The precision (2SE) for 44 &mu;m spot size is 0.000020-0.000040.
The precision (2SE) for 32 &mu;m spot size is 0.000030-0.000050.
