HJ 683-2014 in English

本标准规定了测定环境空气中醛酮类化合物的高效液相色谱法。
本标准适用于环境空气中十三种醛酮类化合物的测定，包括：甲醛、乙醛、丙烯醛、丙酮、丙醛、丁烯醛、甲基丙烯醛、2-丁酮、正丁醛、苯甲醛、戊醛、间甲基苯甲醛和己醛。其他醛酮类化合物经适用性验证也可采用本标准进行分析。
当采样体积为0.05m3 时， 本方法的检出限为0.28μg/m3~1.69μg/m3 ， 测定下限为1.12μg/m3~6.76μg/m3。详见附录A。

Scope

This standard specifies a high-performance liquid chromatography method for the determination of aldehydes and ketones in ambient air. This standard is applicable to the determination of 13 aldehyde and ketone compounds in ambient air, including: formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, methacrolein, 2-butanone, n-butyraldehyde, benzene Formaldehyde, valeraldehyde, m-tolualdehyde and hexanal. Other aldehydes and ketones can also be analyzed using this standard upon verification of applicability. When the sampling volume is 0.05 m, the detection limit of this method is 0.28~1.69 μg/m, and the lower limit of determination is 1.12~6.76 μg/m. See Appendix A for details.
