Abstract: Disclosed are methods and systems for implementing an automated air quality analysis system. The system includes: a sealed enclosure, a filter sample analysis system disposed within the sealed enclosure, and a controller operably coupled with the filter sample analysis system. The filter sample analysis system includes: an automated filter management system with filter samples and an articulating robotic arm which selects the filter sample for analysis, a filter weighing apparatus for weighting of the filter sample, and a primary chemical analysis apparatus for performing electromagnetic energy spectroscopy measurement on the filter sample. The controller operates the automated filter management system to transport the filter sample to the filter weighing apparatus and the primary chemical analysis apparatus, obtains data from the filter sample analysis system, and determines the type and amount of accumulated mass in the sample based on the weight and the spectroscopy measurement result.
