摘　　要：充分干燥的高纯氨包装容器,经反复充装若干次以后,会残留积累愈来愈多的水分。水是高纯氨质量控制的主要指标之一,对于5 N电子级高纯氨,水含量应控制在<5 ppm,对于5.5 N以上纯度的超纯氨,水分更应控制在1 ppm以下。对高纯氨水积累原因进行探讨,并提出解决问题的方法。The package containers dried fully of the high purity ammonia, through filled repeatedly, residual and accumulate water more and more. The water is a major index among the quality control indexes of the high purity ammonia, the water content should be controlled to 〈 5 ppm for the 5 N electronic level high purity ammonia, and the water content should be controlled to 〈 1 ppm for the 5.5 N ultra-high purity ammonia. Probed into the accumulation causes of the water in the high purity ammonia, and then to out forward the resolved method.
