Separation of the nine drugs was satisfactory with use of an intermediately polar HP-17 capillary column. Recoveries of most compounds were excellent for both chloroform/methanol and acetonitrile as elution solvents. However, backgrounds were cleaner and evaporation time was much shorter for the ...
Analysis was performed on a mu-Bondapak C18 column(300 mm x 4.6 mm i.d., 10 microns) with 0.1 mol/L NaH2PO4-methanol(5:1) as the mobile phase and detection at 286 nm. The average recovery of morphine was (101.2 +/- 1.5)% and RSD was 1.5%. The method is simple, rapid, ...
