摘要

Air sampler with (57) [Abstract] automated sample collector switching system (14) (10) are used (70) new sample collector disposed beside the sampling station (12) supplying magazine (25) including (94) store accept magazine accept the (25 '') sample collector. Go to the feed magazine a new collector, to move to the inlet of the magazine from acceptance sampling station spent collector (86) moving mechanism. Plunger or self-closing means (108) to close the entrance of the magazine accepted subsequent to the move to accept magazine spent collector. Feed magazine (70) may include extruding the actuator stack of sample collector included in the magazine. The stack may include a (120) air-impermeable cover that is plugged into it. (86) can be moved to accept both the magazine cover and sample collector moving mechanism. Insertion of the cover to the used sample collector of acceptance in the magazine to reduce the volatilization loss. For the same purpose, the temperature of the receiving magazine can be controlled. The actuators of all of the sample collector the exchange, may be powered by (32) shared vacuum pump which also serves to draw air into the sampling station for air sampling, preferably.
