Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding.

Generally, electric-conductivity materials such as metal, conductive polymers, and graphite are coated on the outside surface of the capillary tip followed by the application of an external high voltage on the tip to provide a sufficient electric field to generate electrospray in seathless interface. Thus, the fabrication of the electric-conductivity material on the surface of fused-silica is one of the main issues when using sheathless interfaces.

一般来说通常需要将金属、导电高分子、或石墨等导电材料涂布於毛细管样品出口尖端，外加第二组电压於导电尖端以提供电喷洒时所需要的电场，但如何将导电材料稳定地涂布於矽氧材质的尖端表面一直是此界面探讨的主题之一。

In this thesis, a pulled bare capillary tip was proposed to be used as the ESI emitter. The outside surface of the tip was neither coated with electric-conductivity materials nor subjected to an external high voltage. Thus, there is no concern such as short lifetime that generally observed in conventional sheathless tips.

本论文尝试直接利用高温拉制及氢氟酸处理过的毛细管尖端做为电喷洒尖端，此设计不需要涂布导电材料及施加第二组电压於毛细管尖端处，此无鞘流界面因此能够避免因导电材料涂布不密合稳定而造成的易脱落及寿命短等问题。
