FIGURE 18.5 Amino NPLC chromatograms of Novel II1412-70 (a) and Neodol 25-12 (b). The inset shows an expanded view of the chromatograms from 28 to 38 min. Reprinted from Murphy et al. (1998b), with permission of the American Chemical Society. 

The solute used in Fig. 18.4 had a fixed alkyl chain length, and as the alkyl distribution increases, one-dimensional NPLC separations become more complex. In Fig. 18.5 the amino silica chromatograms of Novel II1412-70 and Neodol 25-12 are shown, and their corresponding chemical compositions are given in Table 18.2 along with other AE s. 

After collecting 2DLC chromatograms, the data may be presented as EO distributions of individual alkyl components. Figure 18.13 is a plot of the EO distributions across the Cu alkyl component of Neodol 25-12 from Fig. 18.9. The distributions across the C12 component are similar, but with different intensities. Individual NPLC... 

FIGURE 18.13 One-dimensional NPLC chromatograms extracted across the C12 alkyl component from the 2DLC analysis of Neodol 25-12 shown in Fig. 18.9. Times listed are the individual NPLC chromatograms extracted from the 2DLC chromatogram.
