Methods: Active carbon tube adsorption and solvent desorption were used for sampling hexane and analysis was performed by GC(FID).
方法：以活性碳管采集空气中正己烷，用二硫化碳解吸后气相色谱（FID）测定。
Therefore, it is possible to use the cheap solvents (mixture of methanol and water) instead of the expensive hexane and acetone when the Accelerated Solvent Extraction method is employed.
这表明采用加速溶剂提取技术，可用价格较低的甲醇取代昂贵的正己烷和丙酮。
