Nucleopore Sampler

PI: Jean SciareOperators: Christos Keleshis, Maria Kezoudi

The Nucleopore sampler will be located in the nose of the UAV so as to have both inlets extruding at the forefront and avoid any airflow turbulence.

The autopilot and/or the pilot can activate the opening of the valves and powering of the pump –in parallel with GPaC. The autopilot will be set to open a valve and power the pump after stabilizing at a set altitude for a set amount of time. This will allow sampling on a first filter. The pump will then be powered down and the first valve shut off. The autopilot will take the UAV to a second, lower, set altitude at which point the second valve will open and the pump powered again, allowing sampling on the second filter.

The isokinetic inlets are being tested in a wind tunnel.

SEM/EDX analysis will be performed on the filters, delivering 2D size and shape of the particles along with an average elemental composition (elements heavier than oxygen) for each particle, as long as the material is not (too) volatile. Size range typically covered: larger than 400 nm –possibility to lower the limit to 200 or 100nm (increased analysis time). A minimum of 1500 particles to be analyzed for each sample.
