摘　　要：为检验塑料小包装全氟丙烷气体（C3F8）在不同包装和储存方法时浓度变化，将装有5～7mlC3F8的聚氯乙烯小袋，根据不同储藏温度和外包装方法随机分成四组：（1）22℃聚乙烯外包装，（2）36℃聚乙烯外包装，（3）22℃铝箔真空外包装，（4）-29℃聚乙烯外包装；每一组C3F8小袋气体存放一定时间后，应用气相色谱分析方法进行浓度测量。结果：第3组C3F8浓度最高和稳定，第2组浓度随放置时间降低最明显，第4组是临床应用气体的储藏和包装方法，其30天样本浓度和第3组相等，但放置一年时浓度降低。结果显示：塑料小包装C3F8予以铝箔真空外包装是一种可行的方法，利于C3F8运输和普及；聚乙烯外包装的C3F8，应放在-29℃保存，时间不超过一年。To determine the effectiveness of different package and storage for small plastic bag perfluoropropane(C3F8). Four groups of different package and store temperatures were used: 1. Small bag of 5~ 7ml C3F8 packagedwith Polyethylene (PolyE) and stored at 22℃ 1 2. PolyE at 36℃; 3. Aluminum foiled vacuum at 22℃; 4' PolyE at- 29 . The concentrations of C3F8 in each groups were measured with gas chromatography in various storage intervals. The C3F8 concentration was most high and steady in group 3 and was lowest in group 2, The method of group 4which had been used for clinical application showed similar storage effects as group 3' However, the C3F8 concentrationin group 4 was decreased by the end of 1 year. The aluminum foiled vacuum package for small amount C3F8 storage is apractical way to transportation and distribution. The PolyE package and - 29℃ storage can preserve C3FS within oneyear.
