Hello peeps!
I've been browsing around Isodat trying to figure some things out. I came across the Standard Editor and have a few questions.
Who decides the "Value". For example, one of our "working standards" is "Lab N2 tank". The gas is "N2", Delta is "d15N/14N" and Value is "0.971". Where did this number come from?
That same working standard uses the "AirN2" Primary standard whose "Prim. Std. Ratio" is "0.0036782". Should this number be "0.0036764" which is the R15N/14N of Air?
Other working standards have similar configurations but have a different value for N2 such that the "d15N/14N" is 0 vs AirN2, but the primary standard ratio is the same as the "Lab N2 Tank" working standard.
Any information about this tab would be great since the Isodat manual lacks a little bit.
Thanks,
Peter
