1. An autonomous sample capture and analysis system for analyzing aerosol analyte particles in air, the system comprising:
a fresh sample disk or substrate loader station configured to receive a fresh disk cartridge having one or more fresh disks;
a spent sample disk or substrate loader station configured to receive a spent disk cartridge;
an aerosol sample collection station;
a sample disk holder comprising a metal stub and configured to:
removably engage with the fresh disk cartridge disposed at the fresh sample disk station to receive a fresh sample disk;
removably engage with the spent disk cartridge disposed at the spent sample disk station to return a spent sample disk;
hold a fresh sample disk or a spent sample disk; and
move in at least two directions (X-Y-Z) orthogonal to each other using at least one of a stepper motor and actuator using a predetermined analysis sequence; and
one or more analysis stations wherein the aerosol sample collection station is configured to produce a sample spot on a fresh disk when the sample disk holder is positioned at the collection station and wherein the operation of the system is controlled using a microcontroller configured to run a predetermined analysis sequence.
