## separation number, $$\text{SN}$$

in chromatography
https://doi.org/10.1351/goldbook.S05616
This expresses the number of peaks which can be resolved in a given part of the @C01071@ between the peaks of two consecutive n-@A00222@ with $$z$$ and ($$z+1$$) carbon atoms in their molecules: $\text{SN} = \frac{t_{\text{R}\left(z\,+\,1\right)}- t_{\text{R}z}}{w_{\text{h}z}\,+\,w_{\text{h}\left(z+1\right)}} - 1$ In the German literature the symbol $$\text{TZ}$$ (trennzahl) is commonly used to express the separation number. As the separation number depends on the n-@A00222@ used for the calculation, they always must be specified with any given $$\text{SN}$$ value.
