More specifically, in this video I look at a session about one hour in duration, in which a number of kimberlitic perovskites were sampled by laser ablation. Strontium isotope measurements were acquired (on a Nu MC-ICPMS) at 5 Hz (every 0.2 seconds), with an extended period of gas blank (normal operating conditions, but without the laser firing) at the beginning and end of the analysis. Each spot analysis consisted of approx. 60 seconds of ablation, followed by movement to the next spot position, and a short period of gas blank acquisition. The session consisted of fourteen analyses of sample perovskites, bracketed before and after by three measurements of the 83P13 in-house perovskite standard. If you’re really keen on finding out more about the method used, take a look at http://onlinelibrary.wiley.com/doi/10.1111/j.1751-908X.2007.00131.x/abstract
This is another introductory post for those of you who are new to Iolite and are wondering what we mean when we say that Iolite is all about data visualisation. The video gives you a quick tour of what mass spectrometer data looks like in Iolite.
