You mention the question of "were previous u84Sr analysesffected by fractionation drift?" if this is the case is there anything that can be done retrospectively to correct the data?

Yes, in principle any multi-dynamic measurement can be re-processed with fractionation drift correction. This has to be done with the raw mass spectrometer output (intensity and time readings), so this can be either done by the persons who collected the data, or we can do it if they send us their mass spec output files. This is actually a very interesting opportunity for other isotopic systems, especially for 142Nd measurements, where there is a large amount of data that can benefit from such data re-processing. Thanks for the great idea.
