Many aerosol particle sensing instruments benefit from concentrating the incoming particle stream. Aerosol particles can be concentrated using a technique known as virtual impaction. I am currently working an original design. I don’t have a laboratory available so I will first try to build a concentrator similar to versions published in peer-reviewed journals. I will make sure I can reproduce the flow analysis described in these designs before running an analysis of my own design.

Just a coffee cup. I used the decal function to put one of my favorite photos on the face.
