One of these methods involves the use of a pump and sampling head connected by a flexible tube. Air is drawn through
22、the sampling head and chemical agents are trapped for example on a filter, sorption tube, long term detector tube or in a gas washing bottle. The pump and sampling head are attached to the worker so as to collect chemical agents in the breathing zone (personal sampling). The volume of air drawn by t
23、he pump during the sampling period is one of the quantities in the calculation of the concentration of the chemical agents. It is essential that the volume of air sampled is determined accurately. As the volume of air sampled is influenced by the performances of the pump, it is essential that they a
24、re adequate to meet this requirement. EN 482, Workplace atmospheres General requirements for the performance of procedures for the measurement of chemical agents, specifies general performance criteria for methods for measuring the concentration of chemical agents in workplace air.
