Abstract: An identification system for an automated sampling device is disclosed that includes container identifiers to monitor container contaminate levels independently for each container. The containers can include caps having unique identifiers to monitor cap contaminate levels independent from container contaminate levels. The system can include one or more identifier capture devices configured to detect the container and cap identifiers and generate a data signal in response thereto. The data signal can correspond to an identity of each of the container and the cap to store in conjunction with trace elemental analysis of the fluids within the container to monitor contaminate levels of each container and cap. The container and cap identifiers can be laser-marked directly onto one or more surfaces of the container and the cap.
