Chemical slope correction
WebFeb 1, 2003 · The chemical slope is found by regression of the resulting observed δs. A typical value for the chemical slope of δ 40 Ar on the SIO machine is −0.001‰/‰. The δN 2 /Ar values are in almost all cases <10‰, meaning that the chemical slope correction is almost always <0.01‰.

WebNov 9, 2012 · Practical use is limited to emission situations where slope correction factors can be reliably predicted. By making a series of well-defined assumptions and approximations, it is shown how the general formulas reduce to provide an improved theory of orthodox FN-plot data analysis. Taking the natural logarithm of Arrhenius equation yields: Rearranging yields: This has the same form as an equation for a straight line: where x is the reciprocal of T. So, when a reaction has a rate constant that obeys the Arrhenius equation, a …
