摘　　要：介绍了采用特殊填料填充的色谱柱,以GDS-D03氢火焰离子化痕量气体分析仪,通过直接进样的方式分析气体中痕量氯乙烯的方法。通过多次实验对该仪器的分析条件进行优化筛选,从而达到满足食品级二氧化碳中对氯乙烯的控制指标要求。该实验方法稳定可靠、操作简单、检测限可达5×10-9。A gas chromatographic column filled with special fillers and GDS-D03 hydrogen flame ionization trace gas analyzer were introduced. Through several experiments,the analytical conditions of the instrument were optimized and screened,so as to meet the control requirements of vinyl chloride in food grade carbon dioxide. The experimental method is stable and reliable,and the simple detection limit can reach 5 × 10^（-9）.
