FIELD: examination and analysis of materials. SUBSTANCE: device has axial tube one end of which is coupled to medium flow forcing facility through detector, and second end is open. First intermediate tube has one open end, and the other end is fitted with plug through which open end of axial tube is passed. Second intermediate tube has one open end, and the other end is provided with plug through which open end of first intermediate tube is passed and arranged in the latter. External tube has one open end, and the other end is fitted with plug through which open end of second intermediate tube is passed and arranged in the latter. First and second intermediate tubes and external tube are coupled on the side of plugs to medium flow forcing facilities by means of branch pipes. All medium flow forcing facilities are connected to monitoring and control system. EFFECT: more efficient sampling process. 4 dwg
