電噴霧簡單的說就是將液體輸入一施與高電場的噴嘴中，經由電場力及液體表面張力的作用，將液體變成帶電的細小微液滴。在應用上目前大量用於質譜儀中，傳統質譜儀使用的電噴霧噴嘴以不鏽鋼針管作為電噴霧噴射源，並搭配載氣的使用或是在接地電極給予負向電壓作為控制穩定泰勒錐與導入帶電噴霧離子進入質譜儀中的主要型式。
在進行傳統的電噴霧實驗的過程中，當不斷的減少不鏽鋼噴嘴與接地電極的距離時，藉由實驗的觀察，在泰勒錐頂端中，噴霧的射流角度與位移率會產生較大的偏移，整體系統的穩定度表現不佳。且藉由文獻中得知噴霧角錐中表面帶電，故本研究利用電路板雕刻技術來製作實驗電極，試圖改變上電極板與下端接地電極板的位置配置並搭配不同的電壓給予方式，討論其不同電極配置對系統中位移率與偏移角的影響，並找出最佳的電極放置位置與工作參數範圍。

“Electrospray” is a phenomenon when liquid going through a nozzle with high electrical field. Through the interaction between electrical force and surface tension, the liquid becomes charged droplets, which normally utilize in mass spectrometer. Traditional mass spectrometer’s electrospray uses stainless steel needle as an electrospray source. By the help of carrier gas or negative potential ground plate, stabilized Taylor cone can be established and it leads electrospray ion into mass spectrometer.
During the process of traditional electrospray experiments, it is found that the Taylor cone tip will tile and cause a larger skew angle and displacement ratio of the spray if the distance between stainless needle and ground electrode becomes small. Also, it results in the poor performance in the steadiness of whole system. From the literature, the surface of spray pyramid carries electric charges. By changing different types of ground electrodes, the influence of the electrode allocation at displacement ratio and skew angle is investigated. The objective in this studies attempts to find the most appropriate electrode arrangement for stable Taylor cone with minimum skew angle and deflection ratio.
