Presenter Abstract
This work describes the development of a low-cost uncrewed aircraft system (UAS)-mounted air sampler for collecting multiple discrete aerosol samples during a single flight. The system uses a liquid impinger approach in which ambient air is drawn through a collection liquid to capture soluble aerosol material. Multiple sterile collection tubes and a solenoid-controlled flow path allow the sampler to collect separate samples at different locations without landing between collections.
A key design issue in a multi-sample system is contamination between samples. To address this, the payload includes a purge step and a flow layout designed to reduce carryover in shared tubing before each new collection. The design emphasizes simple hardware, low cost, and repeatable operation for field use.
The sampler is being developed for environmental aerosol monitoring near harmful algal blooms (HABs) in South Florida, where remote sampling may reduce operator exposure while improving access to targeted sampling locations.
