ABSTRACT:
An air sampler having an automatic sample collector changer includes a supply magazine for holding a supply of fresh sample collectors and a receiving magazine for receiving and storing used collectors located aside a sampling station. A transfer mechanism transfers a fresh collector from the supply magazine to the sampling station and a used collector from the sampling station to an entrance of the receiving magazine. An automatic closer or plunger closes the entrance of the receiving magazine following transfer thereto of a used collector. The supply magazine can include an actuator for displacing a stack of sample collectors contained in said magazine. This stack may include interspersed air impervious covers. The transfer mechanism can transfer both a sample collector and a cover to the receiving magazine. Interspersing of covers with used sample collectors in the receiving magazine reduces volitization losses. For the same purpose, the temperature of the receiving magazine can be controlled. Preferably, all actuators of the sample collector changer are powered by a common vacuum pump which also serves to draw air into the sampling station for air sampling.
