Short summary

We measure carbonaceous aerosol in Beijing with different sampling configurations and frequencies. It is commonly believed that increasing sampling duration can reduce the influence of the positive sampling artifact and meanwhile does not affect the EC measurement. However, here we demonstrate that this is not necessarily the case. Particularly, we find that the negative sampling artifact of a bare quartz filter could be remarkably enhanced due to the uptake of water vapor by the filter medium.
