还原氮化合物(RNC)，如氨和胺，在大气气溶胶成核、二次有机气溶胶(SOA)和云形成过程中发挥着重要作用。用化学电离质谱仪(CIMS)对氨和胺进行了快速测量。含有RNC的团簇用大气压界面飞行时间质谱仪(API-TOF)或化学电离API-TOF(CI-API-TOF)测量。气溶胶相胺可以用单颗粒质谱仪实时检测，也可以用过滤样品的离线化学分析方法检测。然而，这些仪器在实际大气测量中的应用仍然非常有限。这篇透视文章重点介绍了大气中RNC的最新测量结果，并讨论了它们对新粒子形成(NPF)的影响。
Reduced-nitrogen compounds (RNC), such as ammonia and amines, play important roles in atmospheric aerosol nucleation, secondary organic aerosol (SOA), and cloud formation processes. Fast measurements of ammonia and amines are made with a chemical ionization mass spectrometer (CIMS). Clusters containing RNC are measured with an atmospheric pressure interface time of flight mass spectrometer (APi-TOF) or chemical ionization APi-TOF (CI-APi-TOF). Aerosol-phase amines can be detected with a single particle mass spectrometer at real-time, or with offline chemical analytical methods using filter samples. However, the application of these instruments in real atmospheric measurements is still very limited. This perspective article highlights recent measurements of RNC in the atmosphere and discusses their implications in new particle formation (NPF).
