摘　　要：光纤生产PCVD工艺中,采用高纯度的氧气参与反应,氧气的纯度直接影响光纤的品质。因此,高纯氧气作为一种特气,对纯度的要求越来越高;美国GOW-MAC仪器公司生产的592 DID型气相色谱仪,配置美国GOWMAC仪器公司的放电离子化检测器(DID-Discharge Ionization Detector),使用高效色谱柱,实现了检测高纯氧气中的Ar、N_2、CH_4、H_2、CO_2、C_2H_4、C_2H_2、C_2H_6等杂质的检测。In the PCVD process of optical fiber production, high-purity oxygen is used to participate in the reaction, and the purity of oxygen directly affects the quality of the fiber. Therefore, high purity oxygen as a special gas, the purity requirements are getting higher and higher;the US 569 DID gas chromatograph produced by GOW-MAC Instruments, equipped with the discharge ionization detector (DID-Discharge Ionization Detector)) of GOW-MAC Instruments, USA, using high-efficiency chromatography column to detect the detection of impurities such as Ar, N 2, CH 4, H 2, CO 2, C 2H 4, C 2H 2 and C 2H 6 in high purity oxygen.
