An Aerodyne high-resolution time-of-flight aerosol mass spectrometer(HR-ToF-AMS)was deployed along with other online instruments to study the highly time-resolved chemistry and sources of submicron ae
Higher alkanes are a major class of intermediate-volatility organic compounds(IVOCs),which have been proposed to be an important precursors of secondary organic aerosols(SOA).Accurate estimation of SO
Semivolatile organic compounds(SVOCs)are key precursors to atmospheric particulate matter(PM)which is climate-active.Non-uniform horizontal distribution in the concentrations of volatile organic compo
In this study,PM10 samples at four locations of Loudi,China were collected from January 2017 to March2017 and December 2017 to February 2018 at first.Then,a new analytical strategy of second-order cal
Proton transfer reaction – mass spectrometry(PTR-MS)is a technique of increasing popularity for online monitoring of volatile organic compounds(VOCs).The working principle of PTR-MS is chemical ioniza
