Visualization and optimization of the fluid dynamics in highflow atmospheric pressure ion sources, using the Background Oriented Schlieren method (BOS)

摘要

The AEF changes the fluid dynamics of the ion source signi-ficantly The modified ion source leads to significantly reduced chromatographic peak widths due to the neutral flow optimization The advantages of the BOS method are demonstrated The experimental setup allows the visualization of different gas flows in the source enclosure There is no direct relation between Schlieren images and ion signal
