Best Tracing System

Figure 2 shows traced chromatograms obtained with mixtures of the oxidized compounds with the two solvent systems which give best separation. System lEFW permits distinct separation of all four oxidized compounds. System IFW distinguishes CDG and CSSC clearly but GSSG and DGC merge into one spot. Systems WSPh and CLW are shown be-... 

Hydrogels are used ia the refining of edible oils to adsorb phosphohpids, trace metals, and soaps (103). The adsorption capacity depends on the ease of hydration of the adsorbates, so best performance demands careful control of moisture content ia the system (104). Sihca hydrogel ia combination with alumiaa has beea fouad to be useful for purifyiag used cooking oils ia order to extead their life and enhance the quahty of the fried food (105). 

This observation is important in the study of the chiral recognition mechanism in this system. This may be a practical matter when determining the trace amount of one enantiomer in the presence of its dominant antipode. The smaller peak is always desired to be eluted first for best quantitation. 

Fig. 11 ROCSA spectra for Val-18 of APn-25 fibrils. The C spectrum was measured at 9.39 T under a MAS frequency of 20 kHz. The other spectra were measured at 14.09 T under the frequency of 11 kHz. Upper traces are experimental spectra. Lower traces are best-fit simulations for one-spin system. The rf carrier frequency is at 0 Hz. (Figure and caption adapted from [158].
