Short summary
We present simultaneous measurements of aerosol volatility and carbonaceous matters in Guangzhou, China, in Feb and Mar 2014 using a VTDMA and OC / EC analyzer. Low volatility particles with no significant evaporation at 300° C in the VTDMA contributed 5–15 % of number concentrations of the 40–300 nm particles. Mass closure suggests that non-volatile organic carbon, in addition to elemental carbon, was one of the components of the non-volatile residuals measured by the VTDMA in this study.
