Short summary
Online instruments have been widely applied for the measurement of PM2.5 and its chemical components; however, these instruments have a major shortcoming in terms of the limited number (or lack) of species in field measurements. To this end, a new mass closure PM2.5 online-integrated system was developed and applied in this work to achieve more comprehensive information on chemical species in PM2.5, thus providing a powerful tool for PM2.5 long-term daily measurement and source apportionment.
