摘要： Disclosed is a sampling method which comprises the steps of: blowing airflow towards a center portion of a sampling surface through a blowing port; and sucking the blown airflow from periphery of the sampling surface through a sucking port, or a sampling method which comprises the steps of: providing a sampling device on a sampling surface, the sampling device being shaped to form a sampling space together with the sampling surface, and the sampling device including a blowing port arranged at the center portion of the sampling device and a sucking port arranged at periphery of the sampling device; blowing airflow towards the sampling surface through the blowing port; and sucking the airflow blown towards the sampling surface through the sucking port so as to collect samples. The present application also relates to a sampling device which comprises a housing which is shaped to form a sampling space together with a sampling surface; a blowing port which is provided at a center portion of the housing to blow airflow towards the sampling surface; a sucking port which is provided at periphery of the housing to suck the airflow blown towards the sampling surface. According to the present 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 the periphery together with the airflow and are captured by the sucking device provided at the periphery, thus, a sampling efficiency is improved.
