摘要
用玻璃及不锈钢扩散管进行了气体样品的各种封存、放置方法的试验研究。结果表明,用普通玻璃扩散管盛气、NaCl饱和溶液封闭,倒立放置,在一个月内各气体组分含量变化在±5％范围以内,是一种简便、适用的气体封存、放置方法。
Experimental study on the various methods for sealing and storing gas samples in glass and stainless steel diffusion tubes has been carried out.The result shows that the variation of various gas samples stored upside down in ordinary glass diffusion tubes and sealed with saturated NaCl solution for one month is less than 5%. It is a convenient and appropriate method for sealing and storing gas samples.
