摘　　要：气相色谱测定总挥发性有机化合物(TVOC)的定量依据是一定量的物质在检测器上产生一定强度的响应信号,信号强弱反映物质量的大小。实践发现,在定量过程中,溶剂也会影响物质在检测器上的响应信号强度,使测定结果产生偏差,溶剂是影响检测不可忽视的一个重要因素。The quantitative analysis for the total volatile organic compound （TVOC） by gas chromatography is based on the corresponding response signal which is produced from the substance in the measuring instrument. The intensity of the signal reflects the quantity of the substance. During the process of measurement, it is found that the solvent affects the intensity of the response signal. It may cause the deviation of the measuring result of the substance. Thereby, the solvent is an important factor which affects quantitative analysis.
