It's much importent for the measurment of gas volume when filling and removing in automobile volatile organic compounds (VOC) detection. Compared with constant current gas sampler which is usually used in automobile VOC detection, gas mass flow controller presents excellent stability in complex environment, and the application of gas mass flow controller improves accuracy of automobile VOC detection.% 汽车挥发性有机物组分（VOC）检测过程中，充气和采气体积的计量对检测结果的影响尤为突出。通过气体质量流量控制器与目前VOC检测中常用的恒流气体采样装置的比较，表明在同样满足VOC检测标准要求的情况下，气体质量流量控制器在排除环境干扰等方面体现出更好的稳定性，更有利于汽车VOC检测准确度的提高。
