كروماتوگرافي گازي يک روش فيزيکي است که براي جداسازي، شناسايي و اندازهگيري اجزاي فرار به کار ميرود. به عنوان مثال جدا کردن بنزن (نقطه جوش 1/80) از سيلکوهگزان (نقطه جوش 8/80) بوسيله تقطير جزء به جزء غير ممکن است. در صورتي که آنها را در چند دقيقه ميتوان به کمک کروماتوگرافي گازي جدا نمود و شناسايي کرد. همچنين حدود 200 جزء مختلف نفت خام را به آساني ميتوان تشخيص داد. اين روش سريع و ساده است و براي تشخيص ناخالصيهاي موجود در يک ماده فرار يا مقادير کم مواد ضد آفت در پوست ميوهجات و اندازهگيري گازها و آلودگي مواد به کار مي رود.
