| 摘要 |
The invention relates to a portable hand- and electrically- operated atmospheric pollutant sampling installation which comprises a metal housing (10) with one of the plates (4) made of partially transparent plastic, a sampling probe (A) and apparatus (B) for sampling gas and/or liquid aerosol samples, comprising a flowmeter (9), devices with filter holder (52), electrical intake mini-pumps (35) and a manual pump and a vacuum buffer tank (17) for passing the gas samples outletting the catching apparatus therethrough. Upon operating the pumps (35) the gases to be analysed flow into the probe (A) wherefrom they pass into a device (2) with nozzles, to which the sampling apparatus (B) are connected, said gases being divided into three circuits to be analysed. The aparatus (47) contains some absorbent solutions (45) for catching the gases and the liquid aerosols to be analysed, and the filter holder (52) has a solid (powder) aerosol catching filter (60).
