Sequential air sampler with automatic sample collector changer

An air sampler having an automatic sample collector changer, comprising:

• a sampling station for sampling air to collect a sample on a sample collector;
• a supply magazine for holding a supply of fresh sample collectors;
• a receiving magazine for receiving and storing used collectors from said sampling station following air sampling;
• and
• a transfer mechanism for transferring a fresh sample collector from said supply magazine to the sampling station, a used sample collector from the sampling station to the receiving magazine, and a separate air impervious cover to said receiving magazine.

A sequential air sampler having an automatic sample collector changer, comprising:

• a sampling station for sampling air to collect a sample on a sample collector;
• a supply magazine for holding a supply of fresh sample collectors;
• a receiving magazine for receiving and storing used collectors from said sampling station following air sampling;
• and
• a transfer mechanism for transferring a fresh sample collector from said supply magazine to the sampling station, said transferring fresh sample collector displacing a used sample collector out of said sampling station towards an entrance of said receiving magazine.

• a transfer mechanism for transferring a fresh collector from said supply magazine to the sampling station and a used collector from the sampling station to an entrance of said receiving magazine;
• and
• a temperature controller adjacent the receiving magazine for maintaining used collectors in the receiving magazine at a set temperature.

A sequential air sampler having an automatic sample collector changer, comprising:

• a sampling station for sampling air to collect a sample on a sample collector;
• a supply magazine for holding a stack of fresh sample collectors;
• a receiving magazine for receiving and storing used sample collectors from said sampling station following air sampling;
• a transfer mechanism for transferring a fresh sample collector from said supply magazine to said sampling station and a used sample collector from the sampling station to the receiving magazine;
• an actuator located within said supply magazine for displacing said stack in order to position a fresh sample collector at an uppermost end of said stack for transfer by said transfer mechanism;
• and
• a sensor for confirming proper positioning of the fresh sample collector at the uppermost end of said stack for transfer by said transfer mechanism.
