摘　　要：目的研究蒸汽灭菌器不同蒸汽源及其对蒸汽中非冷凝气体含量的影响。方法采用EN 285-2006推荐的非冷凝气体含量测试方法,对不同蒸汽源及其蒸汽中非冷凝气体含量进行检测与分析。结果A组锅炉房蒸汽经160 m管道输送的蒸汽中非冷凝气体含量平均为12.22%。B3组为自制蒸汽经2.1 m管道输送的蒸汽中非冷凝气体含量平均为8.21%。B1组经除气的反渗透水产的蒸汽中非冷凝气体含量平均为2.42%。B2组未除气的反渗透水产蒸汽中非冷凝气体含量平均为8.05%。结论采用除气水自制蒸汽可有效降低蒸汽中非冷凝气体含量,达到标准要求。Objective To study the different steam sources of steam sterilizers and their effects on the content of non-condensable gases(NCGs)in the steams.Methods The NCGs content test method recommended by EN 285-2006 was used to determine and analyze different steam sources and the content of NCGs in the steams.Results In Group A,the average NCGs content of the steam delivered by 160 m pipelines in the boiler room was 12.22%;in Group B3,the average NCGs content of the self-prepared steam delivered through 2.1 m pipelines was 8.21%;in Group B1,the average NCGs content of the steam produced by degassed reverse osmosis water was 2.42%;in group B2,the average NCGs content of the steam produced by non-degassed reverse osmosis water was 8.05%.Conclusion Using self-prepared degassed water for steam supply may effectively reduce the content of NCGs so as to comply with the standards.
