摘要：Disclosed is a sampling method which comprises the steps of: blowing airflowtowards a center portion of a sampling surface through a blowing port; and sucking theblown airflow from periphery of the sampling surface through a sucking port, or asampling method which comprises the steps of: providing a sampling device on asampling surface, the sampling device being shaped to form a sampling space togetherwith the sampling surface, and the sampling device including a blowing port arranged atthe center portion of the sampling device and a sucking port arranged at periphery ofthe sampling device; blowing airflow towards the sampling surface through the blowingport; and sucking the airflow blown towards the sampling surface through the suckingport so as to collect samples. The present application also relates to a sampling devicewhich comprises a housing which is shaped to form a sampling space together with asampling surface; a blowing port which is provided at a center portion of the housing toblow airflow towards the sampling surface; a sucking port which is provided at peripheryof the housing to suck the airflow blown towards the sampling surface. According to thepresent invention, a blowing airflow having a higher speed is obtained with a lower flow

rate of the blowing airflow, and at the same time, raised particles move towards theperiphery together with the airflow and are captured by the sucking device provided atthe periphery, thus, a sampling efficiency is improved.
