SYSTEM TO REDUCE THE PRESSURE DROP IN A DIFFERENTIAL MOBILITY ANALYZER

System to reduce the pressure drop in a Vienna-type differential mobility analyzer (DMA). It is built to favor the flow axilsymmetry, with no restrictions to avoid strong pressure drops and high pumping capacities. It comprises an electrical isolator, a metallic cone to stabilize the flow, all in on...

Zusammenfassung:System to reduce the pressure drop in a Vienna-type differential mobility analyzer (DMA). It is built to favor the flow axilsymmetry, with no restrictions to avoid strong pressure drops and high pumping capacities. It comprises an electrical isolator, a metallic cone to stabilize the flow, all in one instrument covering a size range of 1 to 600 nm. The electrical isolator is capable of a potential difference of up to 14 kV. It can be used to measure ions and particles in the size range already mentioned with resolutions up to 12.
