A comparatively simple, sensitive and an accurate method was developed for the determination of Benzyl alcohol residues in injectable suspension using EI GC-MS (Electron Ionization Gas chromatography-Mass spectrometer). Using the chromatographic conditions as mentioned above,
a well resolved peak for Benzyl alcohol was obtained at 10.6 minutes of the injection in the
electron ionization mode, which shown in Figure 1. For avoiding matrices which has come in
extraction solution with Benzyl alcohol, we delayed solvent up to 5 min.
