Identification and semi-quantification of nitrooxy organosulfates in aerosol particles by HPLC-MS/MS

Anal. Methods, 2022, 14,2531-2540
DOI: 10.1039/D2AY00460G, Paper
Wenjing Li, Maoyu Cao, Pengxiang Ge, Xiaoyu Fu, Jiajie Tang, Mindong Chen
In this study, we established a HPLC-MS/MS method for the detection of pNOSs. We used SRM scan mode, which is different from other methods. Daily and seasonal variations in the total concentration of pNOSs in Nanjing are presented for the first time.
