Title: Pasi Aalto: Innovator in Particle Analysis Technology
Introduction
Pasi Aalto is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of particle analysis technology, holding two patents that showcase his innovative approach to enhancing the capabilities of analytical systems.
Latest Patents
Aalto's latest patents include a "Method and apparatus for increasing the size of small particles." This invention involves a technique for a condensation particle counter, where an aerosol flow is divided into a sample flow and a sheath flow. The sheath flow is filtered, saturated with vapor, and formed into a vortex flow in a saturator. This vortex flow continues into a condenser, where the sample flow is introduced to the center of the vortex. This process causes the vapor in the saturated sheath flow to condense on the particles in the sample flow, effectively increasing their size.
Another significant patent is the "Sampling device for introduction of samples into an analysis system." This device, which can be a sampling valve, features a turning element with a sampling area designed to retain samples for analysis. The turning element moves between two positions: one where the sampling area is exposed to the material for collection and another where the samples are released for use by the analysis system.
