摘要
在不同的时间段,测定存放于普通球胆及特制的锡箔袋内的一氧化碳标准气的浓度,来探讨其浓度值与贮存时间的关系。通过对3种一氧化碳浓度的测定,证实普通球胆采集的一氧化碳样品,应在当天进行分析;用锡箔气袋,则可保存7~10d。
In order to investigate the variation of the concentration of carbon monoxide with time,we analysed the concentration of carbon monoxide in tinfoil gas collecting bag and ordinary gas collecting bag.The analysis results showed that the concentration of carbon monoxide is changeless for only one day in ordinary gas collecting bag and for 7~10 days in tinfoil gas collecting bag.
