Wide size range fast integrated mobility spectrometer

A mobility spectrometer system to measure a nanometer particle size distribution, said mobility spectrometer system comprising:

• a charger configured to receive a first fluid stream of nanometer particles and to charge said nanometer particles, said charger further configured to direct said first fluid stream of charged nanometer particles into a conduit of a mobility spectrometer;
• a mobility spectrometer in fluid communication with said charger, said mobility spectrometer comprising:
• a conduit configured to receive and provide fluid communication of at least said first fluid stream, said conduit including:
• a separator section configured to generate an electrical field in two dimensions transverse to a dimension associated with the flow of said first fluid stream through said separator section to spatially separate charged nanometer particles of said first fluid stream in said two dimensions and where said electrical field over said separator section is non-uniform in at least a first dimension of said two transverse dimensions;
• and
• a detector disposed downstream of said conduit to detect said spatially-separated nanometer particles.
