【発明の名称】微細電気的スプレー方法及び装置
Document Type and Number:
Japanese Patent JP3350547
Kind Code:
B2
Abstract:
A method of generating an electrospray from a solution is disclosed which is useful for electrospraying at low flow rates, for electrospraying directly into a vacuum, or both. The method comprises the steps of causing the solution to flow through a capillary tube to an outlet opening formed in the terminal portion thereof. The capillary tube terminal portion has an inner diameter of not more than 50 micrometers and an outer diameter of not more than 150 micrometers. An electrical potential difference is provided between the capillary tube terminal portion and a conductor spaced from said terminal portion, with the potential sufficient to cause the solution to electrospray from the capillary outlet. The method is particularly useful for detecting analytes in the solution being electrosprayed by mass spectral analysis.
