Particle mobility calculator

Mobility calculator is an Excel workbook for easy conversions between aerosol particle size and mobility. It allows easy conversions between nanoparticle diameter, mass, and electric mobility. The workbook and the instruction are packed into a zip-file. Additionally, the instruction is available as a separate pdf-file.

Diameter-mobility conversions can be carried out with several options:

· plain Millikan equation,

· constant-updated Millikan equation with arbitrary diameter extension up to 3 nm,

· function-updated Millikan equation according to Tammet (2012),

· function-updated Millikan equation with user-written algorithm of diameter extension,

· approximation by Tammet (1995).
