Data inversion method and error estimate for cascade centripeters

Although centripeters ("virtual impactors") have fewer substrate problems than impactors, their small secondary flows from the impaction regions complicate data analysis. It is shown here how to use data inversion to achieve substantial data improvement. The success of such methods depends upon data error and instrument response. The condition number, which measures error magnification, is defined, discussed, and evaluated for three-stage and five-stage centripeters.
