Figure 1.

Reversed phase gradient elution separation and detection of 10 non-electroactive peptides (name or primary sequence): 1) VGVAPG; 2) GGFL; 3) speract; 4) fibrinopeptide A; 5) octadecaneuropeptide; 6) buccalin; 7) N-f-MLF; 8) ALILTLVS; 10) secretin. The scales of the two chromatograms are not the same; the cathode scale is 3.3 times more sensitive than the anode scale, so that, for normal collection efficiency of about 0.3, the peaks will appear the same size.
