  • Title: Gas-liquid chromatographic determination of nikethamide in injectable preparations.
    Author: Newton JM.
    Journal: J Assoc Off Anal Chem; 1976 Jan; 59(1):93-7. PubMed ID: 1249047.
    Abstract:
    A gas-liquid chromatographic (GLC) method, using a 4% XE-60 on 80-100 mesh Gas-Chrom Q column, a flame ionization detector, and anthracene as the internal standard, has been developed for the direct determination of nikethamide. Eight collaborators analyzed 4 samples, using methanol as the solvent; the coefficients of variation obtained ranged from 1.19 to 3.20%. In a limited study with acetone as the solvent, the coefficients of variation ranged from 0.59 to 1.96%. The GLC method with acetone as a solvent has been adopted as official first action.
