固体物质中气体的分析,大都集中在通过加热或酸溶解来释放气体方而。但这两种方法提供的气体的总含量,没有区分样品中气体的不同形式。加热法受到热解产物的干扰,酸溶解可以因某些反应生成气体产物。 我们研制的装置,可以压碎的样品量为5—1000毫克,并可以对样品中的气体作定性和定量分析。该装置既不吸附所释放的任何气体,也不产生足以干扰分析结果的气体。 The analysis of gases in solid materials is mostly focused on the release of gases by heating or acid dissolution. However, the total gas content provided by these two methods does not differentiate between the different forms of gas in the sample. The heating process is disturbed by the pyrolysis products, which can form gas products due to some reactions. We have developed a device that can crush a sample of 5-1000 mg and can qualitatively and quantitatively analyze the gas in the sample. The device neither adsorbs any released gas nor generates gas that is sufficient to disrupt the result of the analysis.
