2. Gly-Gly-Phe
3. Met-Enkephalin
4. Bradykinin
5. Angiotensin II
6. Angiotensin III
7. Phe-Phe-Phe

Column       : Shodex Asahipak ODP-50 6D (6.0mmID*150mm)
Eluent       : (1): (A); 0.1M NaClO4 + 0.1% Sodium phosphate(pH2)
                    (B); CH3CN
               Linear gradient: 0min to 60min, (A)/(B)=90/10 to 60/40
               (2): (A); 0.1M NaClO4 + 0.1% Sodium phosphate(pH9)
                    (B); CH3CN
               Linear gradient: 0min to 60min, (A)/(B)=90/10 to 60/40
Flow rate    : 1.0mL/min
