Fig. 14.3. Isotachopherogram of the separation of (A) adenosine phosphates and (B) uridine phosphates<br />

in the operational system listed in Table 14.6. (A): 1 = Chloride; 2 = pyrophosphate; 3 = ATP; 4 = ADP;<br />

5 = AMP; 6 = cacodylate. (B): 1 = Chloride; 2 = UTP; 3 = UDP; 4 = UMP; 5 = cacodylate. A thermo-<br />

couple was used for detection.<br />

TABLE 14.4<br />

OPERATIONAL SYSTEM AT pH 4.6 SUITABLE FOR ANIONIC SEPARATIONS (WAnc1II)<br />

This operational system was used only in experiments in which only a thermometric detector was<br />

available.<br />
