Cobalt (II)-Mediated Molecularly Imprinted Polymer as a Monolithic Stationary Phase for Separation of Racemic Citronellal by Liquid Chromatography

Table 7

Enantiomer separation of rac-citronellal on the MMIP B column using the gradient elution method.

Gradient program	(min)	(min)	t0 (min)			α	Rs
X	9.80	10.79	1.72	4.70	5.28	1.12	0.66
Y	39.26	41.83	1.72	21.84	23.33	1.07	1.71

and correspond to the retention time of (S)-(−)-citronellal and (R)-(+)-citronellal, respectively; X: mobile phase and gradient program are the same as in Figure 9; Y: mobile phase and gradient program are the same as in Figure 10.
