标准范围

本文件规定了一种使用反相液相色谱法结合紫外或二极管阵列检测器（LC-UV或LC-DAD）测定蒸气产物排放物中所选羰基化合物（甲醛和乙醛）作为其2,4-二硝基苯腙的量的方法。本文件不包括对其他羰基化合物（如丙烯醛和巴豆醛）的分析，因为之前的工作表明了与这些化合物在用于评估方法性能的电子液体溶液中的稳定性相关的问题[4]。

This document specifies a method for the determination of the amount of selected carbonyl compounds (formaldehyde and acetaldehyde) as their 2,4-dinitrophenylhydrazones in vapour product emissions using reversed phase liquid chromatography coupled with ultraviolet or diode array detector (LC-UV or LC-DAD).This document does not include the analysis of other carbonyl compounds, such as acrolein and crotonaldehyde, due to previous work indicated issues associated with stability of these compounds in the e-liquid solutions that were used to evaluate method performance^[4].
