We have developed a dynamic reference standard of gaseous formaldehyde based on diffusion of the sublimate of trioxane and thermal conversion to formaldehyde in the gas phase. We have also produced a gravimetric standard for formaldehyde in a nitrogen matrix, also by thermal conversion of the sublimate of trioxane. Analysis of the gravimetric standard with respect to the dynamic standard has confirmed the comparability of the static and dynamic gravimetric values.
我们已经开发了一种基于三氧化烷升华物在气相中扩散和热转化为甲醛的气态甲醛动态参考标准。我们还通过三氧化烷升华物的热转化在氮基质中产生了甲醛的重量标准。对重量标准相对于动态标准的分析证实了静态和动态重量值的可比性。
