| Abstract: | A capillary GC method was established for determination of cetyl alcohol and stearyl alcohol in cetostearyl alcohol. A HP-1 quartz capillary column was used with FID as the detector. The temperatures of column, injector and detector were 205, 250 and 250~C, respectively. The calibration curves of cetyl alcohol and stearyl alcohol were linear in the range of 0.05 - 5pg, r=0.9999. The average recoveries were 99.1% and 99.0%, with RSDs of 1.08% and 1.06 %, respectively. |
