Yes, in some cases. For instance, let's suppose you have a dataset with several sessions including analyses of heated/equilibrated gases, carbonate standards, and unknwons samples. In order to reprocess these data in a new reference frame anchored to carbonate standards, you may enter the nominal values of these new carbonate standard in the “Standardization Settings” text box, and rename all your heated/equilibrated gases so that all gases equilibrated at the same temperature are named as a single unknown sample, e.g.,
EG-25... Using the pooled standardization approach will ensure that the gas analyses are fully used to constrain the compositional/gas slope, while still anchoring the final, absolute Δ47 values to the carbonate standards specified in the standardization settings.
For this approach to succeed the follwoing conditions must be met:
