Preferred Label : separation number;
Detailed label : separation number in chromatography, SN;
IUPAC definition : This expresses the number of peaks which can be resolved in a given part of the chromatogram
between the peaks of two consecutive i n /i -alkanes with z and (z 1) carbon atoms
in their molecules: \[{SN} \frac{t_{{R}\left(z\, \,1\right)}- t_{{R}z}}{w_{{h}z}\,
\,w_{{h}\left(z 1\right)}} - 1\] In the German literature the symbol TZ (trennzahl)
is commonly used to express the separation number. As the separation number depends
on the i n /i -alkanes used for the calculation, they always must be specified with
any given SN value.;
