Abstract
A sequential air sampler is provided having a rotatable carrier adapted to support filter cassettes received from a supply magazine at a load station, transport them to a sampling station where gas flow is directed through that cassette, and then be transported to an unload station to be received by a storage magazine. A Geneva driver operated by a single motor provides intermittent rotation to the carrier between fixed positions. A cam rotates in concert with the Geneva driver so that a follower in reciprocating motion pushes up and then pulls down a pair of plungers for simultaneous cassette loading and unloading whenever the carrier is at one of its fixed positions. Magazines have magnetically actuated stoppers to keep the stack of cassettes in place until released. Magazines may also have a retaining lid with a position-adjustable piston to secure cassettes for transport.
