最近我在一篇文献上看到如下的实验条件控制: Gas chromatography experiments (gc) were performed with a Shimadzu gc-16A instrument using a 2m column packed with silicon DC-200 or Carbowax 20m. The nitrogen was used as carrier gas and FID as detector. A temperature programming conditions (120–200℃) was operated for gc experiments. 但是在文献中我发现其要测定的物质的沸点一般都在200-300℃之间，将温度设在120-200℃间是如何检测出来这些物质的，是不是与气相色谱柱的选择有关，求高人指点，不胜感激。
