摘要：

On analyzing some kinds of oils (mineral oils, squalane and esters etc.), the existing analysis method which separates using silica-chromatography and identifies them has some problems, that is, long time-consuming and low efficient. To solve these kinds of problems, in this study, we have analyzed 15 kinds of oils by HPLC and GC and compared experimental data in emulsions like cream and lotion. By these test results, we have known that GC (Varian 3400 system, DB-5; 5% diphenyl 95% dimethyl polysiloxane, FID) can analyze some hydrocarbons and esters with lower carbon number even if it takes long time to analyze them, but HPLC (Waters 2690 pump, 410 detector, HAIsil Silica 5jam, Nova-Pak Cl8 column) can analyze esters and hydrocarbons much faster than GC. However, the detector of HPLC was less sensitive than that of GC.
