Application of Sephadex LH-20 for Microdetermination of Dopamine by Solid Phase Spectrophotometry
Figure 2
The decreases of absorbance of BCG in the Sephadex LH-20 phase in the presence of the various amounts of DP (1-mm cell, similarly packed with Sephadex LH-20 equilibrated with water as reference). [BCG] = 10−4 M, 70 mg Sephadex LH-20; from up to down [DP] = 0.0, 0.4, 0.8, 1.2 and 1.6 μg mL−1.
